What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Prevent plagiarism. Run a free check.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

Writing a Literature Review

In a review of the literature, the writer provides an overview of the most important research and scholarship on a specific topic, problem, or question. (In this context, "literature" refers to the important scholarly sources on a topic, not fiction, poetry, or drama.) The lit review is often said to provide "a map of the field" or "a sense of the scholarly conversation" on a topic.

Purpose and audience of a review of the literature

Before embarking on a research project that adds to the knowledge on a topic, a researcher needs to learn what is already known about the topic. Why? First, there is little point in duplicating knowledge that already exists. Second, the researcher needs to connect their own work to that of other researchers and scholars who work on the same topic. Third, the researcher may want to identify a “gap” in the existing knowledge, a gap the researcher can fill through conducting their own research. Finally, the researcher wants their audience to become familiar with the existing knowledge on the topic.

The audience for a review of the literature usually comprises members of the writer’s own discipline. These disciplinary colleagues may not be specialists in the specific topic or problem addressed in the lit review, however. The writer should keep this in mind when deciding how thoroughly to define or explain specialized concepts.

Forms of a review of the literature

A lit review may be one section of a longer research article. In this case, the lit review often comes after the introduction and before the methods section of the article. This type of lit review typically ends by identifying a gap in the field’s knowledge and posing a set of research questions that will be addressed in the writer’s study.

Some lit reviews are submitted or published as stand-alone documents. In this case, they often conclude by pointing to limitations in perspective or gaps in knowledge that researchers in field should consider addressing.

In the review of the literature, the writer

defines and clarifies the topic, issue, problem, or question they are working with

conveys the current state of knowledge on the topic (etc.) by summarizing the most important sources on it and by identifying connections among those sources, including commonalities and differences

suggests the next step or steps in expanding the topic, solving the problem, or answering the question

The writer of a lit review develops a question and then looks at how other researchers in published studies have addressed it. The writer determines how each source has addressed the question and synthesizes (identifies connections among) the sources. These connections may be topics they address in common, approaches they take to solving the problem, stances they adopt on an issue, or other shared themes.

A review of the literature is not a sequence of summaries

The most common error writers make when composing a lit review is to structure it as a series of summaries. After introducing the issue or question, the writer discusses their first source and how that source addresses that issue or question. Having finished discussing the first source, the writer then moves on to the second source, and so on to the end of the paper. Such a paper does not synthesize the sources, and a lit review requires synthesis.

A lit review should be organized by the topics or themes the sources address. The writer examines their sources, asking, what topics or themes are they discussing? What approaches to the problem are they taking? How are some of their responses to the question similar or different? These topics and themes provide the structure for the lit review.

These are some steps to follow when writing a literature review:

Identify and develop a research question/main idea. 

Example: Research shows that diversity training often fails in workplaces. In what ways does it fail? What needs to be done to have successful diversity training?

Identify the scholarship on your topic and read it critically. Look for the author’s main purpose, the points they make, and the conclusions they reach. Consider how those points relate to your issue, problem, or question. Also consider how their points are supported and whether the evidence and reasoning seems strong and persuasive.

From your source texts, identify the material that is most relevant to your issue, problem, or question. You can highlight it, paste it into a grid or other document (using quotation marks and page numbers!), or take notes on it. This step reduces the amount of source material you have to work with, which can be overwhelming.

From the source material you have identified, look for common topics and themes among the sources. What topics or themes are they discussing? What approaches to the problem are they taking? How are some of their responses to your question similar or different? Based on the topics and themes you see being repeated among sources, outline some main points to address in your review. These points will provide the structure for your paper. 

Example: Some key points in the literature on why diversity training programs are not working are 1) organizations are not managing diversity, 2) diversity training is focused on differences and not on the “valuing” of diversity, 3) training programs are not inclusive of the organization’s entire workforce.

Determine which sources address each of the themes or points you have outlined. You may use a source more than once if it is relevant to more than one point in your outline. 

Determine the order of the points you have identified. Which points should be made before other points? Which order of points tells the best or more logical story?

Draft your lit review. Writing tip: in the body of the lit review, launch paragraphs with a statement of the point you want to make using your source or sources. Then discuss the source(s). Using this strategy, you help readers keep your points in mind and allow them to follow the argument you are making or the story you are telling in your lit review. Compare:

The Joint Legislative and Audit Commission produced a 2014 report on the causes of increased tuition in Virginia. The bipartisan commission spend two years analyzing the data and found that the decrease in public funding accounted for over half the increase in tuition over the last ten years.

A major cause of increased tuition is a decrease in public funding. According to the Joint Legislative and Audit Commission (2014), the decrease in Virginia’s public funding for higher education accounted for over half the increase in tuition over the last ten years (p. 7). In another study, researchers found….

• Cite and document sources appropriately. Be sure to introduce the research studies appropriately in your text as well, using a documentation style relevant to your field, e.g. APA, MLA, Chicago, CSE.

How To Write A Literature Review - A Complete Guide

Table of Contents

A literature review is much more than just another section in your research paper. It forms the very foundation of your research. It is a formal piece of writing where you analyze the existing theoretical framework, principles, and assumptions and use that as a base to shape your approach to the research question.

Curating and drafting a solid literature review section not only lends more credibility to your research paper but also makes your research tighter and better focused. But, writing literature reviews is a difficult task. It requires extensive reading, plus you have to consider market trends and technological and political changes, which tend to change in the blink of an eye.

Now streamline your literature review process with the help of SciSpace Copilot. With this AI research assistant, you can efficiently synthesize and analyze a vast amount of information, identify key themes and trends, and uncover gaps in the existing research. Get real-time explanations, summaries, and answers to your questions for the paper you're reviewing, making navigating and understanding the complex literature landscape easier.

In this comprehensive guide, we will explore everything from the definition of a literature review, its appropriate length, various types of literature reviews, and how to write one.

What is a literature review?

A literature review is a collation of survey, research, critical evaluation, and assessment of the existing literature in a preferred domain.

Eminent researcher and academic Arlene Fink, in her book Conducting Research Literature Reviews , defines it as the following:

“A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.

Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic, and to demonstrate to your readers how your research fits within a larger field of study.”

Simply put, a literature review can be defined as a critical discussion of relevant pre-existing research around your research question and carving out a definitive place for your study in the existing body of knowledge. Literature reviews can be presented in multiple ways: a section of an article, the whole research paper itself, or a chapter of your thesis.

A literature review does function as a summary of sources, but it also allows you to analyze further, interpret, and examine the stated theories, methods, viewpoints, and, of course, the gaps in the existing content.

As an author, you can discuss and interpret the research question and its various aspects and debate your adopted methods to support the claim.

What is the purpose of a literature review?

A literature review is meant to help your readers understand the relevance of your research question and where it fits within the existing body of knowledge. As a researcher, you should use it to set the context, build your argument, and establish the need for your study.

What is the importance of a literature review?

The literature review is a critical part of research papers because it helps you:

• Gain an in-depth understanding of your research question and the surrounding area
• Convey that you have a thorough understanding of your research area and are up-to-date with the latest changes and advancements
• Establish how your research is connected or builds on the existing body of knowledge and how it could contribute to further research
• Elaborate on the validity and suitability of your theoretical framework and research methodology
• Identify and highlight gaps and shortcomings in the existing body of knowledge and how things need to change
• Convey to readers how your study is different or how it contributes to the research area

How long should a literature review be?

Ideally, the literature review should take up 15%-40% of the total length of your manuscript. So, if you have a 10,000-word research paper, the minimum word count could be 1500.

Your literature review format depends heavily on the kind of manuscript you are writing — an entire chapter in case of doctoral theses, a part of the introductory section in a research article, to a full-fledged review article that examines the previously published research on a topic.

Another determining factor is the type of research you are doing. The literature review section tends to be longer for secondary research projects than primary research projects.

What are the different types of literature reviews?

All literature reviews are not the same. There are a variety of possible approaches that you can take. It all depends on the type of research you are pursuing.

Here are the different types of literature reviews:

Argumentative review

It is called an argumentative review when you carefully present literature that only supports or counters a specific argument or premise to establish a viewpoint.

Integrative review

It is a type of literature review focused on building a comprehensive understanding of a topic by combining available theoretical frameworks and empirical evidence.

Methodological review

This approach delves into the ''how'' and the ''what" of the research question —  you cannot look at the outcome in isolation; you should also review the methodology used.

Systematic review

This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research and collect, report, and analyze data from the studies included in the review.

Meta-analysis review

Meta-analysis uses statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects than those derived from the individual studies included within a review.

Historical review

Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and identify future research's likely directions.

Theoretical Review

This form aims to examine the corpus of theory accumulated regarding an issue, concept, theory, and phenomenon. The theoretical literature review helps to establish what theories exist, the relationships between them, the degree the existing approaches have been investigated, and to develop new hypotheses to be tested.

Scoping Review

The Scoping Review is often used at the beginning of an article, dissertation, or research proposal. It is conducted before the research to highlight gaps in the existing body of knowledge and explains why the project should be greenlit.

State-of-the-Art Review

The State-of-the-Art review is conducted periodically, focusing on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic and highlights where there are still disagreements.

Can you use the first person in a literature review?

When writing literature reviews, you should avoid the usage of first-person pronouns. It means that instead of "I argue that" or "we argue that," the appropriate expression would be "this research paper argues that."

Do you need an abstract for a literature review?

Ideally, yes. It is always good to have a condensed summary that is self-contained and independent of the rest of your review. As for how to draft one, you can follow the same fundamental idea when preparing an abstract for a literature review. It should also include:

• The research topic and your motivation behind selecting it
• A one-sentence thesis statement
• An explanation of the kinds of literature featured in the review
• Summary of what you've learned
• Conclusions you drew from the literature you reviewed
• Potential implications and future scope for research

Here's an example of the abstract of a literature review

Is a literature review written in the past tense?

Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present perfect tenses.

How many sources for a literature review?

There are multiple approaches to deciding how many sources to include in a literature review section. The first approach would be to look level you are at as a researcher. For instance, a doctoral thesis might need 60+ sources. In contrast, you might only need to refer to 5-15 sources at the undergraduate level.

The second approach is based on the kind of literature review you are doing — whether it is merely a chapter of your paper or if it is a self-contained paper in itself. When it is just a chapter, sources should equal the total number of pages in your article's body. In the second scenario, you need at least three times as many sources as there are pages in your work.

Quick tips on how to write a literature review

To know how to write a literature review, you must clearly understand its impact and role in establishing your work as substantive research material.

You need to follow the below-mentioned steps, to write a literature review:

• Outline the purpose behind the literature review
• Search relevant literature
• Examine and assess the relevant resources
• Discover connections by drawing deep insights from the resources
• Structure planning to write a good literature review

1. Outline and identify the purpose of  a literature review

As a first step on how to write a literature review, you must know what the research question or topic is and what shape you want your literature review to take. Ensure you understand the research topic inside out, or else seek clarifications. You must be able to the answer below questions before you start:

• How many sources do I need to include?
• What kind of sources should I analyze?
• How much should I critically evaluate each source?
• Should I summarize, synthesize or offer a critique of the sources?
• Do I need to include any background information or definitions?

Additionally, you should know that the narrower your research topic is, the swifter it will be for you to restrict the number of sources to be analyzed.

2. Search relevant literature

Dig deeper into search engines to discover what has already been published around your chosen topic. Make sure you thoroughly go through appropriate reference sources like books, reports, journal articles, government docs, and web-based resources.

You must prepare a list of keywords and their different variations. You can start your search from any library’s catalog, provided you are an active member of that institution. The exact keywords can be extended to widen your research over other databases and academic search engines like:

• Google Scholar
• Microsoft Academic
• Science.gov

Besides, it is not advisable to go through every resource word by word. Alternatively, what you can do is you can start by reading the abstract and then decide whether that source is relevant to your research or not.

Additionally, you must spend surplus time assessing the quality and relevance of resources. It would help if you tried preparing a list of citations to ensure that there lies no repetition of authors, publications, or articles in the literature review.

3. Examine and assess the sources

It is nearly impossible for you to go through every detail in the research article. So rather than trying to fetch every detail, you have to analyze and decide which research sources resemble closest and appear relevant to your chosen domain.

While analyzing the sources, you should look to find out answers to questions like:

• What question or problem has the author been describing and debating?
• What is the definition of critical aspects?
• How well the theories, approach, and methodology have been explained?
• Whether the research theory used some conventional or new innovative approach?
• How relevant are the key findings of the work?
• In what ways does it relate to other sources on the same topic?
• What challenges does this research paper pose to the existing theory
• What are the possible contributions or benefits it adds to the subject domain?

Be always mindful that you refer only to credible and authentic resources. It would be best if you always take references from different publications to validate your theory.

Always keep track of important information or data you can present in your literature review right from the beginning. It will help steer your path from any threats of plagiarism and also make it easier to curate an annotated bibliography or reference section.

4. Discover connections

At this stage, you must start deciding on the argument and structure of your literature review. To accomplish this, you must discover and identify the relations and connections between various resources while drafting your abstract.

A few aspects that you should be aware of while writing a literature review include:

• Rise to prominence: Theories and methods that have gained reputation and supporters over time.
• Constant scrutiny: Concepts or theories that repeatedly went under examination.
• Contradictions and conflicts: Theories, both the supporting and the contradictory ones, for the research topic.
• Knowledge gaps: What exactly does it fail to address, and how to bridge them with further research?
• Influential resources: Significant research projects available that have been upheld as milestones or perhaps, something that can modify the current trends

Once you join the dots between various past research works, it will be easier for you to draw a conclusion and identify your contribution to the existing knowledge base.

5. Structure planning to write a good literature review

There exist different ways towards planning and executing the structure of a literature review. The format of a literature review varies and depends upon the length of the research.

Like any other research paper, the literature review format must contain three sections: introduction, body, and conclusion. The goals and objectives of the research question determine what goes inside these three sections.

Nevertheless, a good literature review can be structured according to the chronological, thematic, methodological, or theoretical framework approach.

How to write a literature review in 6 steps

What is a literature review?

How to write a literature review, 1. determine the purpose of your literature review, 2. do an extensive search, 3. evaluate and select literature, 4. analyze the literature, 5. plan the structure of your literature review, 6. write your literature review, other resources to help you write a successful literature review, frequently asked questions about writing a literature review, related articles.

A literature review is an assessment of the sources in a chosen topic of research.

A good literature review does not just summarize sources. It analyzes the state of the field on a given topic and creates a scholarly foundation for you to make your own intervention. It demonstrates to your readers how your research fits within a larger field of study.

In a thesis, a literature review is part of the introduction, but it can also be a separate section. In research papers, a literature review may have its own section or it may be integrated into the introduction, depending on the field.

➡️ Our guide on what is a literature review covers additional basics about literature reviews.

• Identify the main purpose of the literature review.
• Do extensive research.
• Evaluate and select relevant sources.
• Analyze the sources.
• Plan a structure.
• Write the review.

In this section, we review each step of the process of creating a literature review.

In the first step, make sure you know specifically what the assignment is and what form your literature review should take. Read your assignment carefully and seek clarification from your professor or instructor if needed. You should be able to answer the following questions:

• How many sources do I need to include?
• What types of sources should I review?
• Should I evaluate the sources?
• Should I summarize, synthesize or critique sources?
• Do I need to provide any definitions or background information?

In addition to that, be aware that the narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good overview of the topic.

Now you need to find out what has been written on the topic and search for literature related to your research topic. Make sure to select appropriate source material, which means using academic or scholarly sources , including books, reports, journal articles , government documents and web resources.

➡️ If you’re unsure about how to tell if a source is scholarly, take a look at our guide on how to identify a scholarly source .

Come up with a list of relevant keywords and then start your search with your institution's library catalog, and extend it to other useful databases and academic search engines like:

• Google Scholar
• Science.gov

➡️ Our guide on how to collect data for your thesis might be helpful at this stage of your research as well as the top list of academic search engines .

Once you find a useful article, check out the reference list. It should provide you with even more relevant sources. Also, keep a note of the:

• authors' names
• page numbers

Keeping track of the bibliographic information for each source will save you time when you’re ready to create citations. You could also use a reference manager like Paperpile to automatically save, manage, and cite your references.

Read the literature. You will most likely not be able to read absolutely everything that is out there on the topic. Therefore, read the abstract first to determine whether the rest of the source is worth your time. If the source is relevant for your topic:

• Read it critically.
• Look for the main arguments.
• Take notes as you read.
• Organize your notes using a table, mind map, or other technique.

Now you are ready to analyze the literature you have gathered. While your are working on your analysis, you should ask the following questions:

• What are the key terms, concepts and problems addressed by the author?
• How is this source relevant for my specific topic?
• How is the article structured? What are the major trends and findings?
• What are the conclusions of the study?
• How are the results presented? Is the source credible?
• When comparing different sources, how do they relate to each other? What are the similarities, what are the differences?
• Does the study help me understand the topic better?
• Are there any gaps in the research that need to be filled? How can I further my research as a result of the review?

Tip: Decide on the structure of your literature review before you start writing.

There are various ways to organize your literature review:

• Chronological method : Writing in the chronological method means you are presenting the materials according to when they were published. Follow this approach only if a clear path of research can be identified.
• Thematic review : A thematic review of literature is organized around a topic or issue, rather than the progression of time.
• Publication-based : You can order your sources by publication, if the way you present the order of your sources demonstrates a more important trend. This is the case when a progression revealed from study to study and the practices of researchers have changed and adapted due to the new revelations.
• Methodological approach : A methodological approach focuses on the methods used by the researcher. If you have used sources from different disciplines that use a variety of research methods, you might want to compare the results in light of the different methods and discuss how the topic has been approached from different sides.

Regardless of the structure you chose, a review should always include the following three sections:

• An introduction, which should give the reader an outline of why you are writing the review and explain the relevance of the topic.
• A body, which divides your literature review into different sections. Write in well-structured paragraphs, use transitions and topic sentences and critically analyze each source for how it contributes to the themes you are researching.
• A conclusion , which summarizes the key findings, the main agreements and disagreements in the literature, your overall perspective, and any gaps or areas for further research.

The goal of a literature review is to asses the state of the field on a given topic in preparation for making an intervention.

A literature review should have its own independent section. You should indicate clearly in the table of contents where it can be found, and address this section as “Literature Review.”

There is no set amount of words for a literature review; the length depends on the research. If you are working with a large amount of sources, then it will be long. If your paper does not depend entirely on references, then it will be short.

Most research papers include a literature review. By assessing the available sources in your field of research, you will be able to make a more confident argument about the topic.

Literature reviews are most commonly found in theses and dissertations. However, you find them in research papers as well.

How To Structure Your Literature Review

3 options to help structure your chapter.

By: Amy Rommelspacher (PhD) | Reviewer: Dr Eunice Rautenbach | November 2020 (Updated May 2023)

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As  we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

• Demonstrate your knowledge of the research topic
• Identify the gaps in the literature and show how your research links to these
• Provide the foundation for your conceptual framework (if you have one)
• Inform your own  methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter. 

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess. 

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write. 

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an  introduction , a  body   and a  conclusion . 

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you  will   and  won’t   be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies). 

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way. 

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking)  three options  for organising your literature review.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

• What is the earliest literature published relating to this topic?
• How has the field changed over time? Why?
• What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

Here are some questions to ask yourself when structuring your literature review by themes:

• Are there any patterns that have come to light in the literature?
• What are the central themes and categories used by the researchers?
• Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed  methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question  how  existing research has been conducted, as opposed to  what  the conclusions and/or findings the research were.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

• Which methodologies have been utilised in this field?
• Which methodology is the most popular (and why)?
• What are the strengths and weaknesses of the various methodologies?
• How can the existing methodologies inform my own methodology?

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve  discussed how to structure your literature review for maximum impact. Here’s a quick recap of what  you need to keep in mind when deciding on your literature review structure:

• Just like other chapters, your literature review needs a clear introduction , body and conclusion .
• The introduction section should provide an overview of what you will discuss in your literature review.
• The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
• The conclusion section should draw together the key findings of your literature review and link them to your research questions.

Great work. This is exactly what I was looking for and helps a lot together with your previous post on literature review. One last thing is missing: a link to a great literature chapter of an journal article (maybe with comments of the different sections in this review chapter). Do you know any great literature review chapters?

I agree with you Marin… A great piece

I agree with Marin. This would be quite helpful if you annotate a nicely structured literature from previously published research articles.

Awesome article for my research.

I thank you immensely for this wonderful guide

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

• Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

How to Write a Literature Review

An introduction to and a guide on how to write your next literature review

Become a Visual Thinker

Preparing for a Literature Review

Clearly define the topic of your research, this is the basis of picking what articles you'll be reading, analyzing and summarizing, and subsequently including in your research topic. Narrowing down the topic allows you to have a more specific base of literature to read, analyze, and review.

What is a Literature Review?

A literature review is a portion of a research paper that compiles, describes, and analyzes different sources of information relevant to a given research topic, and then draws connections between each source to one another and the research of the author writing the review. Rather than simply describing each of the sources, critical reviews of the sources should be made.

Literature Review Purpose

A literature review is important for a variety of reasons, beyond just providing a background for your research topic. The purpose of the literature review is to:

Discuss current questions and debates that exist in the research topic

Provide a summary of the relevant aspects of the sources reviewed

Show how your research paper is placed chronologically in the research topic

Provide an overall understanding and introduction to the topic, building credibility

Prevent the author from researching a topic or area that has already been done

How to Develop a Literature Review for Theses and Dissertations

The first step in developing the literature review for theses and dissertations is to collect information and sources that are related to the topic area you are researching.

1. Keyword search

There are a variety of different places to find relevant further research for your topic. University or public library catalogs are a good place to search, as well as online databases such as Google Scholar. When searching for relevant sources, try to use keywords that are related to your topic. When you find a few really good sources, look at their literature reviews and bibliographies to find other literature in the field.

2. Snowballing

Read as many sources in your field as possible to fully understand what work has been done in the past and where the current status of the topic lies. This could be journal articles, publications, books, and interviews, to name just a few.

Take notes as you are reading the different sources. I personally like to download my sources in my theses as pdfs and then highlight relevant information and annotate in the margins, using Adobe Acrobat Reader.

Once you have read and annotated bibliography of the relevant sources, then analyze the collected works and categorize them from most and least relevant to the subject you are discussing. One effective method for doing this is by utilizing a reading grid.

A reading grid can be broken down by source information individually for each source included in the theses or dissertation literature review, such as the research question, methodology, findings, limitations, and areas for future research. This allows you to easily see the most relevant information within each piece of literature. An example of this can be seen below, provided by OpenAcademics and adapted from Auckland University of Technology.

View this example in greater detail here .

3. Citations 

Citing a source means giving the credit for the source used in your research paper. This includes the information that you get from books or scholarly articles, and even pictures, charts or graphs. It is essential to give credit where it is due, so that you do not plagiarize another person's work.

You will need to include citations when you are using specific information from a single source, or when you are paraphrasing an idea from a single source. Citations can help avoid any confusion that would arise if someone else reads your work, and they can help direct readers to further resources on your topic.

When writing a literature review it is essential to keep track of all of the sources that you use. You should compile all of the sources into one document so that you can refer back to them easily and know what information came from which source. This will make it easier for you when you are ready to write your paper and insert citations.

There is a citation style that is specific to each discipline, and you should always follow the standards for your field. Check with your instructor or supervisor if you have any questions about the citation style you should use.

How to format citations

To make sure your paper is as perfect as it can be, let's take a look at how to format citations. If you're using Microsoft Word to write your literature review, you can use the "References" tab to organize your citations. If you want more control over the formatting, or if you're using another type of word processing program, you can do it manually.

Starting with a few basics

Double space everything, including block quotes and bibliography entries. If you're using a citation tool like Zotero or EndNote, make sure the formatting preferences are set for double spacing.For citations, you can use a standard font (like Times New Roman or Arial) in size 12. Using 1-inch margins all around for citations is common practice. To make sure your citations look good, indenting each new citation by half an inch is a good practice. (if you press Tab at the beginning of a paragraph, that should work).

Literature Review Length

The number of concepts explored and the number of sources incorporated into the literature review will determine its length. The number of sources included depend on how narrow or broad the topic is, the level of agreement among researchers in the topic, and the desired depth of analysis.

If the topic of your research is incredibly specific, there may only be a limited number of sources to choose from for your review, whereas if it is a really broad topic, you may need to include a variety of sources to paint a full picture of the topic background. Additionally, if there is a lot of disagreement within the research topic, you may need to include more sources to show the varying opinion that exists.

Introduction to the Literature Review

This section should describe how your research topic is placed in the context of the existing literature in the field, and provide a reasoning for reviewing the literature that has been selected. Additionally the methodology for finding these sources should be discussed, and the order of the selected literature should be explained — whether it is running chronologically, based on theme of sources, or some other methodological manner.

Body of the Literature Review

The best approach for the body of the literature review is to break it down into sections or paragraphs for each of the sources reviewed. Within each literature source discussion, there should be the following components:

Description of the context of the literature and a summary of the most important concepts and aspects

Explanations of theories, equations, and terminology, relevant to the topic

Discussion of aspects of the literature that connect to your research topic

Conclusion of the Literature Review

Within the conclusion of the literature review, the entire section should be summarized and connected together in a methodical manner. To achieve this, the conclusion should provide the following:

A summarized overview of the important concepts, flaws, and gaps in each of the reviewed sources.

A description of how the literature is tied together, and a discussion of how the topic being written about also contributes to the overall field of knowledge.

You should show that the sources provided in the literature review relate to the work that is to be discussed in your research topic. Directly discuss different aspects of the literature review that contributed to the concepts, ideas, methodology, results, and conclusions in your research. If your research addresses potential gaps in past literature, you can also highlight this here.

An effective method for meeting this conclusion is to first synthesize the works with a brief introduction, a comparison of agreeing and disagreeing points of view, and stating the research findings impact. Then finalize the conclusion by pointing out the limitations of the topic, its impact, and discussing the contribution of your own work to this field.

An example of this synthesis and contribution discussion can be seen below, provided by OpenAcademics and adapted from Auckland University of Technology.

What is a literature review?

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

What is the purpose of literature review?

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 

2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Conducting a literature review

Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1  

Choose a Topic and Define the Research Question:

• Select a topic that is relevant to your field of study. 
• Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:

• Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
• Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
• Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:

• Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
• Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:

• Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
• Record and document your search strategy for transparency and replicability. 
• Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:

• Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
• Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
• Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
• Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
• Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:

• Literature review outline should be based on themes, chronological order, or methodological approaches. 
• Write a clear and coherent narrative that synthesizes the information gathered. 
• Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
• Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research.

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic.

How to write a literature review introduction (+ examples)

The introduction to a literature review serves as your reader’s guide through your academic work and thought process. Explore the significance of literature review introductions in review papers, academic papers, essays, theses, and dissertations. We delve into the purpose and necessity of these introductions, explore the essential components of literature review introductions, and provide step-by-step guidance on how to craft your own, along with examples.

Why you need an introduction for a literature review

A literature review is a comprehensive examination of the international academic literature concerning a particular topic. It involves summarizing published works, theories, and concepts while also highlighting gaps and offering critical reflections.

In academic writing , the introduction for a literature review is an indispensable component. Effective academic writing requires proper paragraph structuring to guide your reader through your argumentation. This includes providing an introduction to your literature review.

It is imperative to remember that you should never start sharing your findings abruptly. Even if there isn’t a dedicated introduction section .

Instead, you should always offer some form of introduction to orient the reader and clarify what they can expect.

When you need an introduction for a literature review

What to include in a literature review introduction.

It is crucial to customize the content and depth of your literature review introduction according to the specific format of your academic work.

In practical terms, this implies, for instance, that the introduction in an academic literature review paper, especially one derived from a systematic literature review , is quite comprehensive. Particularly compared to the rather brief one or two introductory sentences that are often found at the beginning of a literature review section in a standard academic paper. The introduction to the literature review chapter in a thesis or dissertation again adheres to different standards.

By addressing these elements, your introduction will provide a clear and structured overview of what readers can expect in your literature review paper.

In some cases, you might include:

Introduction to a literature review chapter in thesis or dissertation

The literature review typically constitutes a distinct chapter within a thesis or dissertation. Often, it is Chapter 2 of a thesis or dissertation.

Examples of literature review introductions

Example 1: an effective introduction for an academic literature review paper.

To begin, let’s delve into the introduction of an academic literature review paper. We will examine the paper “How does culture influence innovation? A systematic literature review”, which was published in 2018 in the journal Management Decision.

Example 2: An effective introduction to a literature review section in an academic paper

The paper begins with a general introduction and then proceeds to the literature review, designated by the authors as their conceptual framework. Of particular interest is the first paragraph of this conceptual framework, comprising 142 words across five sentences:

Examples 3-5: Effective introductions to literature review chapters

The introduction to a literature review chapter can vary in length, depending largely on the overall length of the literature review chapter itself. For example, a master’s thesis typically features a more concise literature review, thus necessitating a shorter introduction. In contrast, a Ph.D. thesis, with its more extensive literature review, often includes a more detailed introduction.

• General comments

A literature review should be structured like any other essay: it should have an introduction, a middle or main body, and a conclusion.

The introduction should:

• define your topic and provide an appropriate context for reviewing the literature;
• establish your reasons – i.e. point of view – for
• reviewing the literature;
• explain the organisation – i.e. sequence – of the review;
• state the scope of the review – i.e. what is included and what isn’t included. For example, if you were reviewing the literature on obesity in children you might say something like: There are a large number of studies of obesity trends in the general population. However, since the focus of this research is on obesity in children, these will not be reviewed in detail and will only be referred to as appropriate.

The middle or main body should:

• organise the literature according to common themes;
• provide insight into the relation between your chosen topic and the wider subject area e.g. between obesity in children and obesity in general;
• move from a general, wider view of the literature being reviewed to the specific focus of your research.

The conclusion should:

• summarise the important aspects of the existing body of literature;
• evaluate the current state of the literature reviewed;
• identify significant flaws or gaps in existing knowledge;
• outline areas for future study;
• link your research to existing knowledge.

A synthesis matrix helps you record the main points of each source and document how sources relate to each other.

After summarizing and evaluating your sources, arrange them in a matrix or use a citation manager to help you see how they relate to each other and apply to each of your themes or variables.  

By arranging your sources by theme or variable, you can see how your sources relate to each other, and can start thinking about how you weave them together to create a narrative.

Introduction

Once you have your literature review planned out, you are ready to begin writing! Good organization and a clear focus are key to writing a successful academic paper of any kind, which is why the previous steps in this guide are so important; the more thorough you are with each of the preceding elements of writing the literature review, the easier this final step will be.

A literature review is organized into an introduction, multiple body paragraphs, and a conclusion. This format should be familiar to you, as it is the general outline of most academic essays; what is new and exciting about this literature review is the information you've gathered in your research and synthesized in your organization and outlining process.

Remember, if you ever need help with writing an essay of any kind, the ACPHS Writing Center is here to help! You can book an appointment with one of the peer tutors or reach out by email. The Library is also here to provide assistance with your assignments, particularly finding or citing resources.

Intro Paragraph & Thesis

Introductory paragraphs can be the most challenging part of writing a paper. Instead of laying out the evidence (or in the case of a literature review, analyzing your resources), you must first provide background information and context for the topic, discuss the body of literature in general as well as the scope of your review, and give a brief outline of how you will organize the review.

It is generally a good idea to open an introduction with a hook, or an interesting first sentence. This could be a statistic or fact about the topic that you find relevant, a rhetorical question that will be answered in the rest of the introduction, or even an appropriate anecdote. The point of a strong hook is to catch the reader's attention; for a literature review, it can help get the reader invested in the research around your topic, as well as your analysis of it.

Some authors prefer to write their introductory paragraph after completing the body of the essay, finding it easier to summarize what will be shared with the reader after it has already been written. There is no right or wrong order for crafting your paper, so if this method appeals to you then you should make use of it. However, with appropriately detailed planning it can be simple to write out an introduction prior to the body. Using an outline  (using the methods provided by Walden University, for example) can make writing the introduction and the entire essay much simpler.

Your literature review's introduction should contain four major elements:

• Establishing the topic, including providing background information and any necessary definitions to make sure your reader has all the context necessary to understand the rest of the literature review
• The trends or themes of the research that you noticed while compiling your sources, including any that you will use to organize your literature
• The purpose, criteria, and scope of the literature review: how will the literature be organized? What is your reason for examining this topic? What will you be analyzing about the sources (comparing/contrasting research methodology, conclusions, etc.)? Is there any literature you decided not to include -- if so, what disqualified it from the review?
• Introduce your thesis statement by drawing on the previous 3 components of the introduction to state what you discovered about the literature on this topic. Specifically, the thesis should answer where the current literature's strengths and weaknesses lie, and where additional research may be needed

The purpose of the introduction is to make sure that your reader has all the information they need to understand and appreciate your literature review, and to provide them a general blueprint of the analysis and arguments you will be making.

• 5 Questions to Strengthen Your Thesis Statement by the University of Guelph Digital Learning Commons

Body Paragraphs

With the introduction out of the way -- or perhaps even before you've written the introduction -- it's time to examine the literature you've gathered. We established how to organize the literature in the previous section of this guide, and that organization will serve as the framework for the body paragraphs. For example, if you organized your literature into themes, then each theme would serve as its own paragraph, in which you'd compare and contrast the sources within each theme; if you organized it by methodology or historical era, each of those would be a body paragraph.

As you write your literature analyses, keep the following recommendations in mind, provided by Shona McCombes at Scribbr :

Summarize  and synthesize:  give an overview of the main points of each source and combine them into a coherent whole Analyze and interpret:  don’t just  paraphrase  other researchers—add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole Critically evaluate:  mention the strengths and weaknesses of your sources Write in well-structured paragraphs:  use  transition words  and  topic sentences  to draw connections, comparisons and contrasts

Your summary of each source can be as detailed as is appropriate, based on how important the source is to the overall literature or how much analysis you have to perform on it. In general, the more significant a source is to your review, the more time should be devoted to summarizing and analyzing it.

While looking at individual sources, remember to keep connecting them back to the theme of the body paragraph and the overall thesis; explaining their relevance in a particular section of literature helps the reader follow along and better understand your overall arguments.

Other useful tips to keep in mind when writing your body paragraphs, provided by the Writing Center of the University of North Carolina at Chapel Hill :

• Use evidence to support your claims
• Be selective, and focus on the most important points for each piece of literature rather than trying to describe everything
• Use quotes when appropriate, but know that literature reviews do not frequently require direct quotations
• Paraphrase accurately
• Literature Reviews by the University of North Carolina at Chapel Hill's Writing Center

Conclusion & Reviewing Your Paper

Concluding Paragraph

A conclusion is used to provide further reinforcement of the arguments presented throughout the paper. In general, this consists of briefly summarizing the body paragraphs and reasserting their connection to your thesis. This is also good practice for a literature review; in addition, your conclusion should again summarize the broad trends of the research on your topic, as well as any opportunities for additional or more thorough research that you've found. 

Below are some helpful recommendations for writing conclusions, compiled from advice explained in more detail in the links below:

• Address the broader implications of the existing research, and why it is important to close the gaps you evaluated during your literature review
• Include a quotation or fact that effectively illustrates your thesis in a provocative or interesting way
• Use simple, clear language without jargon
• Reestablish your thesis and its connection with the literature reviewed

Your goal with the concluding paragraph of your literature review should be to leave the reader with a firm understanding of the existing literature on your topic, where additional research may be necessary, and why it matters.

Revising Your Literature Review

Revision is a process that goes beyond simply correcting spelling and grammar mistakes -- though proofreading is an important part of the writing process as well. The purpose of revising your literature review before submission is to look at it the way your reader will and pick up on any potential leaps of logic, unclear explanations, or shoddy evidence. The revision process should not begin immediately after finishing the paper; whenever possible, wait a few hours or days before looking at your draft, so that you can approach it with fresh eyes. 

When revising, focus on major issues with the paper such as organization, clarity, and thoroughness. Trying to both revise your writing and proofread it for small spelling or grammar issues may distract you from more important areas that could be improved. Ask yourself if your thesis is well-defended by the body paragraphs, and if you still agree with the conclusions you stated in the introduction. If more or better arguments are needed, find places in the body paragraphs to add evidence or make clearer connections to your thesis. Focus on the flow of the review; does each body paragraph move naturally into the next one? Do your paragraphs need to be reordered or restructured?

After major revisions are done, it is time to proofread for spelling, grammar, and general writing errors. Try reading the paper out loud and seeing where your word choice could be strengthened or a run-on sentence could be amended.

It can sometimes be difficult to revise an essay on your own, so consider booking an appointment with the ACPHS Writing Center to go over your writing with a tutor. Friends, classmates, or your professor can also be useful sources of feedback, and if possible try to get as many different readers to look over your writing and provide insight.

How to Write a Literature Review

• What Is a Literature Review
• What Is the Literature

Writing the Review

Why Are You Writing This?

There are two primary points to remember as you are writing your literature review:

• Stand-alone review: provide an overview and analysis of the current state of research on a topic or question
• Research proposal: explicate the current issues and questions concerning a topic to demonstrate how your proposed research will contribute to the field
• Research report: provide the context to which your work is a contribution.
• Write as you read, and revise as you read more. Rather than wait until you have read everything you are planning to review, start writing as soon as you start reading. You will need to reorganize and revise it all later, but writing a summary of an article when you read it helps you to think more carefully about the article. Having drafts and annotations to work with will also make writing the full review easier since you will not have to rely completely on your memory or have to keep thumbing back through all the articles. Your draft does not need to be in finished, or even presentable, form. The first draft is for you, so you can tell yourself what you are thinking. Later you can rewrite it for others to tell them what you think.

General Steps for Writing a Literature Review

Here is a general outline of steps to write a thematically organized literature review. Remember, though, that there are many ways to approach a literature review, depending on its purpose.

• Stage one: annotated bibliography. As you read articles, books, etc, on your topic, write a brief critical synopsis of each. After going through your reading list, you will have an abstract or annotation of each source you read. Later annotations are likely to include more references to other works since you will have your previous readings to compare, but at this point the important goal is to get accurate critical summaries of each individual work.
• Stage two: thematic organization. Find common themes in the works you read, and organize the works into categories. Typically, each work you include in your review can fit into one category or sub-theme of your main theme, but sometimes a work can fit in more than one. (If each work you read can fit into all the categories you list, you probably need to rethink your organization.) Write some brief paragraphs outlining your categories, how in general the works in each category relate to each other, and how the categories relate to each other and to your overall theme.
• Stage three: more reading. Based on the knowledge you have gained in your reading, you should have a better understanding of the topic and of the literature related to it. Perhaps you have discovered specific researchers who are important to the field, or research methodologies you were not aware of. Look for more literature by those authors, on those methodologies, etc. Also, you may be able to set aside some less relevant areas or articles which you pursued initially. Integrate the new readings into your literature review draft. Reorganize themes and read more as appropriate.
• Stage four: write individual sections. For each thematic section,  use your draft annotations (it is a good idea to reread the articles and revise annotations, especially the ones you read initially) to write a section which discusses the articles relevant to that theme. Focus your writing on the theme of that section, showing how the articles relate to each other and to the theme, rather than focusing your writing on each individual article. Use the articles as evidence to support your critique of the theme rather than using the theme as an angle to discuss each article individually.
• Stage five: integrate sections. Now that you have the thematic sections, tie them together with an introduction, conclusion, and some additions and revisions in the sections to show how they relate to each other and to your overall theme.

Specific Points to Include

More specifically, here are some points to address when writing about specific works you are reviewing. In dealing with a paper or an argument or theory, you need to assess it (clearly understand and state the claim) and analyze it (evaluate its reliability, usefulness, validity). Look for the following points as you assess and analyze papers, arguments, etc. You do not need to state them all explicitly, but keep them in mind as you write your review:

• Be specific and be succinct. Briefly state specific findings listed in an article, specific methodologies used in a study, or other important points. Literature reviews are not the place for long quotes or in-depth analysis of each point.
• Be selective. You are trying to boil down a lot of information into a small space. Mention just the most important points (i.e. those most relevant to the review's focus) in each work you review.
• Is it a current article? How old is it? Have its claims, evidence, or arguments been superceded by more recent work? If it is not current, is it important for historical background?
• What specific claims are made? Are they stated clearly?
• What evidence, and what type (experimental, statistical, anecdotal, etc) is offered? Is the evidence relevant? sufficient?
• What arguments are given? What assumptions are made, and are they warranted?
• What is the source of the evidence or other information? The author's own experiments, surveys, etc? Historical records? Government documents? How reliable are the sources?
• Does the author take into account contrary or conflicting evidence and arguments? How does the author address disagreements with other researchers?
• What specific conclusions are drawn? Are they warranted by the evidence?
• How does this article, argument, theory, etc, relate to other work?

These, however, are just the points that should be addressed when writing about a specific work. It is not an outline of how to organize your writing. Your overall theme and categories within that theme should organize your writing, and the above points should be integrated into that organization. That is, rather than write something like:

     Smith (2019) claims that blah, and provides evidence x to support it, and says it is probably because of blip. But Smith seems to have neglected factor b.      Jones (2021) showed that blah by doing y, which, Jones claims, means it is likely because of blot. But that methodology does not exclude other possibilities.      Johnson (2022) hypothesizes blah might be because of some other cause.

list the themes and then say how each article relates to that theme. For example:

     Researchers agree that blah (Smith 2019, Jones 2021, Johnson 2022), but they do not agree on why. Smith claims it is probably due to blip, but Jones, by doing y, tries to show it is likely because of blot. Jones' methodology, however, does not exclude other possibilities. Johnson hypothesizes ...

Reference & Instruction Librarian

What is a Literature Review?

A literature review is not:

• just a summary of the sources
• a grouping of broad, unrelated sources
• a compilation of everything that has been written on a particular topic
• literature criticism (think English) or a book review.

So, what is it then?

A literature review :

• Surveys all of the scholarship that has been written about a particular topic (your research question).
• Provides a description , summary , and evaluation of each scholarly work.
• Synthesizes and organizes the previous research by comparing and contrasting the findings or methodology of those previous writings.

"A literature review is an account of what has been published on a topic by accredited scholars and researchers. Occasionally, you will be asked to write one as a separate assignment, ..., but more often, it is part of the introduction to an essay, research report, or thesis. In writing the literature review, you aim to convey to your reader what knowledge and ideas have been established on a topic and their strengths and weaknesses. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available or a set of summaries."  

A literature review is an integrated analysis-- not just a summary-- of scholarly writings that are related directly to your research question.  That is, it represents the literature that provides background information on your topic and shows a correspondence between those writings and your research question.

A literature review may be a stand-alone work or the introduction to a more extensive research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.

Where Can I Find a Lit Review?

The Literature Review portion of a scholarly article is usually close to the beginning. It often follows the introduction , or may be combined with the introduction. The writer may discuss his or her research question first, or may choose to explain it while surveying previous literature.

If you are lucky, there will be a section heading that includes " literature review ".  If not, look for the section of the article with the most citations or footnotes .

This could either be the easy bit or the difficult bit, depending on your experiences. Some find searching to be arduous and frustrating, but then find synthesising and analysing what they've found to be much easier - or vice versa. 

Remember : a literature review is NOT a summary . It should be a piece of writing that combines, analyses and evaluates what is currently known and published about a particular topic.It's important to make sure the literature review is structured, organised, and analytical. Make sure you have organised the literature in a comprehensive manner, and kept it consistent throughout.

Just like any other academic paper, a literature review consists of three main sections: an introduction or background information section; the body of the review containing the discussion of sources; and, finally, a conclusion and/or recommendations section to end the paper.

For some help with academic writing, please see this extensive resources from the University of North Carolina. It explores almost any type of academic writing or assignment type you can think of, including literature reviews   https://writingcenter.unc.edu/tips-and-tools/

Your introduction should specify your literature review topic and how it is relevant to your field/discipline overall.  It briefly highlights the relevant issues or debates that have characterised your field of research. It should also include some signposting for the reader, explaining the organisation/sequence of topics covered, and the scope of your survey. As with any other research paper, your introduction should preview the conclusions that you will come to, based on your analysis and evaluation.

Your conclusion should summarise the results of your analysis and the current state of the research in your field as analysed in the main body. It should identify any gaps or problems with the existing research, and explain how your own research is going to address these gaps or build on the existing research.

Feedback Poll

We would love feedback if this page was useful to you! If you have additional questions please reach out to us and we can try our best to help.

The main, and largest, section of your literature review is the body. Here you will write an analysis of the literature according to whichever organisation method you have decided upon. 

You can write your literature review one section at a time, but make sure you read through them all to check they link together and tell a coherent "story".  This should show how your research builds on what has been done before. Based on previous research, you provide justifications for what you are studying, why you are studying it, and how you are going to do it.

It is important to know that you don't have to refer to everything in the same depth  in your literature review. You are usually expected to prioritise recent research. Some scientific research that was crucial in the past is now out of date. For instance, there may be a few older studies that were important in starting research in the field, but their methods have been surpassed by more accurate methods. You only need to demonstrate your awareness of these older, dated studies in a few sentences, then move on to discussing in greater depth the up-to-date methods and why they are more accurate.

Sample literature review paragarph

The below points are some guidelines for composing your literature review. Here is a sample paragraph (from a literature review about sexism and language) to illustrate what these points look like in practice: 

However, other studies have shown that even gender-neutral antecedents are more likely to produce masculine images than feminine ones (Gastil, 1990). Hamilton (1988) asked students to complete sentences that required them to fill in pronouns that agreed with gender-neutral antecedents such as “writer,” “pedestrian,” and “persons.” The students were asked to describe any image they had when writing the sentence. Hamilton found that people imagined 3.3 men to each woman in the masculine “generic” condition and 1.5 men per woman in the unbiased condition. Thus, while ambient sexism accounted for some of the masculine bias, sexist language amplified the effect.

( Source: Erika Falk and Jordan Mills, “Why Sexist Language Affects Persuasion: The Role of Homophily, Intended Audience, and Offense,” Women and Language 19:2 ).

Use evidence

In the example above, the writers refer to several other sources when making their point. A literature review in this sense is just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence to show that what you are saying is valid.

Be selective

Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the review’s focus, whether it is thematic, methodological, or chronological.

Use quotes sparingly

Falk and Mills, the authors of the sample paragraph, do not use any direct quotes. That is because the survey nature of the literature review does not allow for in-depth discussion or detailed quotes from the text. Some short quotes here and there are okay, though, if you want to emphasize a point, or if what the author said just cannot be rewritten in your own words. Notice that Falk and Mills do quote certain terms that were coined by the author, not common knowledge, or taken directly from the study. But if you find yourself wanting to put in more quotes, check with your lecturer.

Summarise and synthesise

Remember to summarise and synthesise your sources within each paragraph as well as throughout the review. The authors here recap important features of Hamilton’s study, but then synthesise it by rephrasing the study’s significance and relating it to their own work.

K ep your own  voice

While the literature review presents others’ ideas, your voice (the writer’s) should remain front and center. Notice that Falk and Mills weave references to other sources into their own text, but they still maintain their own voice by starting and ending the paragraph with their own ideas and their own words. The sources support what Falk and Mills are saying.

Use caution when paraphrasing

When paraphrasing a source that is not your own, be sure to represent the author’s information or opinions accurately and in your own words. In the example above, Falk and Mills either directly refer in the text to the author of their source, such as Hamilton, or they provide ample notation in the text when the ideas they are mentioning are not their own , for example, they mentioned a source from Gastil, 1990.

How to write a Literature Review?

Components:

• Introduction: State your research topic
• Body/Presentation of Sources Used: A research topic have different angles/viariables/themes. Organize your finding based of those categories.
• Discussion/Analysis of Literature: Summarize/synthesize major literature that deal with your research topic. Discuss common themes, gaps, etc...
• Conclusion: Re-state your topic and explain if it has changed after the review and what are the next steps for your research
• Do not over "quote." If you only quote from every single author you found, then you are not showing any original thinking or analysis. Use quotes judiciously. Use quotes to highlight a particular passages or thought that is exemplary of the research, theory or topic you are researching.
• Instead use paraphrasing to report, in your own words, what the author was reporting or theorizing.
• Summarize findings, important sections or a whole article--this is different from paraphrasing since you are not re-stating the author words but identifying the main points of what you are reading in a concise matter for your readers.
• When synthesizing your findings for the literature review (this is when make comparison, establish relationships between authors' works, point out weakness, strenghts and gaps among the literature review, you still need to give credit to these sources.

WRITING THE REVIEW 

You've done the research and now you're ready to put your findings down on paper. When preparing to write your review, first consider how will you organize your review.

The actual review generally has 5 components:

Abstract  -  An abstract is a summary of your literature review. It is made up of the following parts:

• A contextual sentence about your motivation behind your research topic
• Your thesis statement
• A descriptive statement about the types of literature used in the review
• Summarize your findings
• Conclusion(s) based upon your findings

Introduction :   Like a typical research paper introduction, provide the reader with a quick idea of the topic of the literature review:

• Define or identify the general topic, issue, or area of concern. This provides the reader with context for reviewing the literature.
• Identify related trends in what has already been published about the topic; or conflicts in theory, methodology, evidence, and conclusions; or gaps in research and scholarship; or a single problem or new perspective of immediate interest.
• Establish your reason (point of view) for reviewing the literature; explain the criteria to be used in analyzing and comparing literature and the organization of the review (sequence); and, when necessary, state why certain literature is or is not included (scope)  - 

Body :  The body of a literature review contains your discussion of sources and can be organized in 3 ways-

• Chronological -  by publication or by trend
• Thematic -  organized around a topic or issue, rather than the progression of time
• Methodical -  the focusing factor usually does not have to do with the content of the material. Instead, it focuses on the "methods" of the literature's researcher or writer that you are reviewing

You may also want to include a section on "questions for further research" and discuss what questions the review has sparked about the topic/field or offer suggestions for future studies/examinations that build on your current findings.

Conclusion :  In the conclusion, you should:

Conclude your paper by providing your reader with some perspective on the relationship between your literature review's specific topic and how it's related to it's parent discipline, scientific endeavor, or profession.

Bibliography :   Since a literature review is composed of pieces of research, it is very important that your correctly cite the literature you are reviewing, both in the reviews body as well as in a bibliography/works cited. To learn more about different citation styles, visit the " Citing Your Sources " tab.

How to Write a Literature Review? A Beginner’s Guide

Sooner or later in your academic path, you will be required to compose a literature review. So, it’s important to approach this task well-prepared and understand how to write a literature review inside out. 

Are you interested in how to write lit review projects correctly and cover the subject comprehensively, from all angles? This article will explore the concept of review of literature , dwell on how to write a literature review in line with your professor’s expectations, and share a universal literature review template for your usage. 

What Is the Purpose of a Literature Review? 

To understand what should be included in a literature review , you need to understand its purpose and value in a larger work. A well-researched and written lit review usually addresses the following objectives: 

• Inform . The fundamental purpose of any review of literature is to provide the foundation of knowledge on a specific topic or phenomenon. You explore what people have learned about it from prior studies and summarize those findings to inform your readers. 
• Give credit . Another purpose of a lit review is to identify researchers who have contributed to the advancement of research on your chosen literature review topic and have produced the most valuable findings. This way, you pay tribute to those researchers and showcase your knowledge of the most considerable influencers. 
• Identify gaps . By performing a thorough review of literature , you may not only discover what is known about your topic but also find out what it yet to be learned about it. As a result of reviewing the available evidence, you may identify gaps for addressing through your academic inquiry. 
• Identify patterns . Those who know how to write a literature review can also effectively embrace data trends and patterns in the collected dataset. As a result, they can present a more nuanced analysis of the existing knowledge in your literature review and uncover dependencies that inform people’s understanding of certain phenomena and processes.  
• Contextualize research . When you perform lit review writing, you can also create a spot for your own study within the broad field of your academic research interest. This way, you show to your readers that you can effectively navigate the landscape of your academic area. 

These purposes lay the foundation for understanding how to write a literature review that will attain all academic goals. You simply need to use this list as your checklist for structuring an impactful lit review and including all vital data in it. 

How to Write a Literature Review? 

Now, we come to the main topic of this article – how to write a good literature review for dissertation projects, research papers, and other works. Follow the steps we’ve covered below to arrive at a consistent, logical piece of lit review . 

Identify Relevant Sources 

Any literature review writing starts with academic research. You should look for sources that explore your topic from various angles and provide valuable literature review findings to expand your knowledge on the subject. It’s best to look for subject-specific books first and then go through academic databases that publish journal articles. This way, you will start with the evidence of the highest reliability level and move on to expand your literature review dataset conveniently. 

Screen Sources for Quality 

The best solution on how to write a literature review without challenges is to rely on high-quality evidence. Your task is to research extensively in reliable academic databases to find peer-reviewed academic journals and books written by experts in your field. Don’t over-rely on online sources in your literature review, like blogs or opinion pieces, because they rarely possess the needed degree of credibility for an academic review. By choosing only industry-approved sources from qualified professionals, you can build a solid foundation for your writing and impress the audience. 

Determine Data Patterns and Gaps 

How to write a literature review of value for your readers? One of the best approaches is to go beyond mere summarization of what other researchers have found on the subject and to apply critical thinking and data categorization. This way, you will manage to uncover existing patterns and trends and examine those dependencies in your literature review. A systematic, critical approach is always evaluated much higher than a simple outline of what people say on your subject. 

Draft an Outline 

Now, it’s time to compose an outline for a literature review . The outline should include the main concepts you’re planning to cover in the literature review text and should structure the narrative consistently. By means of composing an outline before the actual writing process, you give yourself a hands-on roadmap for composing a logically flowing piece. As a result of using an outline, you will write the literature review faster and will avoid the risk of going off-topic. 

Compose the Review 

With a good and detailed outline, you should have no more problems or concerns about how to write a literature review . The writing process should go quickly and smoothly when you have all your evidence at your fingertips, categorized by themes and requiring only proper summarization in the text. 

We recommend starting with a broad introduction to the topic and concepts related to it. You should give definitions and explain the topic’s features and components that require attention in the research process. After that, you may briefly outline the main sections of your review and then proceed to the exploration of each section in depth. 

At times, your professor will give you a specific structure for review writing – such as the general introduction, coverage of theories, and then coverage of empirical evidence. At times, it may be a review of the data search strategy and a report on the identified resources that follow. In any case, you should follow the tutor’s prompt closely to ensure compliance with the task. 

Make Use of This Generic Literature Review Template 

Looking for a universal, ready-to-use literature review template ? Here is an effective literature review template that everyone can apply with minor tweaks to produce a high-quality review of literature . 

LITERATURE REVIEW TEMPLATE 

Introduction 

• Introduce the topic of your literature review 
• Examine its significance for your academic area 
• Determine the scope of your literature review inquiry 
• Give a brief outline of subtopics and sections included in your literature review 

Body of the literature review

• Describe the subtopic and indicate how it relates to your literature review’s main idea
• Summarize the evidence available about it 
• Compare the available data and voice your opinion 

Conclusion 

• Summarize the main points and findings from your literature review 
• State the main contribution you have managed to achieve 
• Identify the research gaps your literature review has revealed 

Use this literature review template to pump your writing muscle and get ready for new literature review challenges. 

More Pro Tips for Writing a Literature Review 

If you’re still unsure about how to do a literature review with excellence, these pro tips may improve your understanding of this task type. 

• Mind the audience . Understanding how to do a literature review for a research paper often has little to do with how to write literature review for thesis . This difference is explained by the fact that these types of academic work are of different lengths and pursue different scholarly goals. This way, you may need to cover only some basic seminal research in the review of literature for a research paper but will need to dig deeper into theoretical and applied research with deeper analysis and more critical thinking when dealing with a thesis.
• Mind the length . How long should a literature review be ? This is a vital question that you should answer before starting the outlining and writing process. Ask your professor if you’re not sure or apply the rule of thumb, where this section usually takes from 15% to 25% of the entire paper. 
• Mind the structure . It’s important to cover all lit review aspects that your professor wants to see in the paper; otherwise, you risk getting a low grade even if your literature review is comprehensive and interesting. What should a literature review include ? In most cases, you will be required to cover some seminal research works in your literature review to show that you understand who the pioneers in the field are, and what contribution they have made to the topic’s exploration. Next, you should examine relevant theories that inform studies in your subject. At the end of the literature review, you should typically cite a variety of studies of applied nature, thus showing what empirical research is conducted in your academic field.

Introductions

What this handout is about.

This handout will explain the functions of introductions, offer strategies for creating effective introductions, and provide some examples of less effective introductions to avoid.

The role of introductions

Introductions and conclusions can be the most difficult parts of papers to write. Usually when you sit down to respond to an assignment, you have at least some sense of what you want to say in the body of your paper. You might have chosen a few examples you want to use or have an idea that will help you answer the main question of your assignment; these sections, therefore, may not be as hard to write. And it’s fine to write them first! But in your final draft, these middle parts of the paper can’t just come out of thin air; they need to be introduced and concluded in a way that makes sense to your reader.

Your introduction and conclusion act as bridges that transport your readers from their own lives into the “place” of your analysis. If your readers pick up your paper about education in the autobiography of Frederick Douglass, for example, they need a transition to help them leave behind the world of Chapel Hill, television, e-mail, and The Daily Tar Heel and to help them temporarily enter the world of nineteenth-century American slavery. By providing an introduction that helps your readers make a transition between their own world and the issues you will be writing about, you give your readers the tools they need to get into your topic and care about what you are saying. Similarly, once you’ve hooked your readers with the introduction and offered evidence to prove your thesis, your conclusion can provide a bridge to help your readers make the transition back to their daily lives. (See our handout on conclusions .)

Note that what constitutes a good introduction may vary widely based on the kind of paper you are writing and the academic discipline in which you are writing it. If you are uncertain what kind of introduction is expected, ask your instructor.

Why bother writing a good introduction?

You never get a second chance to make a first impression. The opening paragraph of your paper will provide your readers with their initial impressions of your argument, your writing style, and the overall quality of your work. A vague, disorganized, error-filled, off-the-wall, or boring introduction will probably create a negative impression. On the other hand, a concise, engaging, and well-written introduction will start your readers off thinking highly of you, your analytical skills, your writing, and your paper.

Your introduction is an important road map for the rest of your paper. Your introduction conveys a lot of information to your readers. You can let them know what your topic is, why it is important, and how you plan to proceed with your discussion. In many academic disciplines, your introduction should contain a thesis that will assert your main argument. Your introduction should also give the reader a sense of the kinds of information you will use to make that argument and the general organization of the paragraphs and pages that will follow. After reading your introduction, your readers should not have any major surprises in store when they read the main body of your paper.

Ideally, your introduction will make your readers want to read your paper. The introduction should capture your readers’ interest, making them want to read the rest of your paper. Opening with a compelling story, an interesting question, or a vivid example can get your readers to see why your topic matters and serve as an invitation for them to join you for an engaging intellectual conversation (remember, though, that these strategies may not be suitable for all papers and disciplines).

Strategies for writing an effective introduction

Start by thinking about the question (or questions) you are trying to answer. Your entire essay will be a response to this question, and your introduction is the first step toward that end. Your direct answer to the assigned question will be your thesis, and your thesis will likely be included in your introduction, so it is a good idea to use the question as a jumping off point. Imagine that you are assigned the following question:

Drawing on the Narrative of the Life of Frederick Douglass , discuss the relationship between education and slavery in 19th-century America. Consider the following: How did white control of education reinforce slavery? How did Douglass and other enslaved African Americans view education while they endured slavery? And what role did education play in the acquisition of freedom? Most importantly, consider the degree to which education was or was not a major force for social change with regard to slavery.

You will probably refer back to your assignment extensively as you prepare your complete essay, and the prompt itself can also give you some clues about how to approach the introduction. Notice that it starts with a broad statement and then narrows to focus on specific questions from the book. One strategy might be to use a similar model in your own introduction—start off with a big picture sentence or two and then focus in on the details of your argument about Douglass. Of course, a different approach could also be very successful, but looking at the way the professor set up the question can sometimes give you some ideas for how you might answer it. (See our handout on understanding assignments for additional information on the hidden clues in assignments.)

Decide how general or broad your opening should be. Keep in mind that even a “big picture” opening needs to be clearly related to your topic; an opening sentence that said “Human beings, more than any other creatures on earth, are capable of learning” would be too broad for our sample assignment about slavery and education. If you have ever used Google Maps or similar programs, that experience can provide a helpful way of thinking about how broad your opening should be. Imagine that you’re researching Chapel Hill. If what you want to find out is whether Chapel Hill is at roughly the same latitude as Rome, it might make sense to hit that little “minus” sign on the online map until it has zoomed all the way out and you can see the whole globe. If you’re trying to figure out how to get from Chapel Hill to Wrightsville Beach, it might make more sense to zoom in to the level where you can see most of North Carolina (but not the rest of the world, or even the rest of the United States). And if you are looking for the intersection of Ridge Road and Manning Drive so that you can find the Writing Center’s main office, you may need to zoom all the way in. The question you are asking determines how “broad” your view should be. In the sample assignment above, the questions are probably at the “state” or “city” level of generality. When writing, you need to place your ideas in context—but that context doesn’t generally have to be as big as the whole galaxy!

Try writing your introduction last. You may think that you have to write your introduction first, but that isn’t necessarily true, and it isn’t always the most effective way to craft a good introduction. You may find that you don’t know precisely what you are going to argue at the beginning of the writing process. It is perfectly fine to start out thinking that you want to argue a particular point but wind up arguing something slightly or even dramatically different by the time you’ve written most of the paper. The writing process can be an important way to organize your ideas, think through complicated issues, refine your thoughts, and develop a sophisticated argument. However, an introduction written at the beginning of that discovery process will not necessarily reflect what you wind up with at the end. You will need to revise your paper to make sure that the introduction, all of the evidence, and the conclusion reflect the argument you intend. Sometimes it’s easiest to just write up all of your evidence first and then write the introduction last—that way you can be sure that the introduction will match the body of the paper.

Don’t be afraid to write a tentative introduction first and then change it later. Some people find that they need to write some kind of introduction in order to get the writing process started. That’s fine, but if you are one of those people, be sure to return to your initial introduction later and rewrite if necessary.

Open with something that will draw readers in. Consider these options (remembering that they may not be suitable for all kinds of papers):

• an intriguing example —for example, Douglass writes about a mistress who initially teaches him but then ceases her instruction as she learns more about slavery.
• a provocative quotation that is closely related to your argument —for example, Douglass writes that “education and slavery were incompatible with each other.” (Quotes from famous people, inspirational quotes, etc. may not work well for an academic paper; in this example, the quote is from the author himself.)
• a puzzling scenario —for example, Frederick Douglass says of slaves that “[N]othing has been left undone to cripple their intellects, darken their minds, debase their moral nature, obliterate all traces of their relationship to mankind; and yet how wonderfully they have sustained the mighty load of a most frightful bondage, under which they have been groaning for centuries!” Douglass clearly asserts that slave owners went to great lengths to destroy the mental capacities of slaves, yet his own life story proves that these efforts could be unsuccessful.
• a vivid and perhaps unexpected anecdote —for example, “Learning about slavery in the American history course at Frederick Douglass High School, students studied the work slaves did, the impact of slavery on their families, and the rules that governed their lives. We didn’t discuss education, however, until one student, Mary, raised her hand and asked, ‘But when did they go to school?’ That modern high school students could not conceive of an American childhood devoid of formal education speaks volumes about the centrality of education to American youth today and also suggests the significance of the deprivation of education in past generations.”
• a thought-provoking question —for example, given all of the freedoms that were denied enslaved individuals in the American South, why does Frederick Douglass focus his attentions so squarely on education and literacy?

Pay special attention to your first sentence. Start off on the right foot with your readers by making sure that the first sentence actually says something useful and that it does so in an interesting and polished way.

How to evaluate your introduction draft

Ask a friend to read your introduction and then tell you what they expect the paper will discuss, what kinds of evidence the paper will use, and what the tone of the paper will be. If your friend is able to predict the rest of your paper accurately, you probably have a good introduction.

Five kinds of less effective introductions

1. The placeholder introduction. When you don’t have much to say on a given topic, it is easy to create this kind of introduction. Essentially, this kind of weaker introduction contains several sentences that are vague and don’t really say much. They exist just to take up the “introduction space” in your paper. If you had something more effective to say, you would probably say it, but in the meantime this paragraph is just a place holder.

Example: Slavery was one of the greatest tragedies in American history. There were many different aspects of slavery. Each created different kinds of problems for enslaved people.

2. The restated question introduction. Restating the question can sometimes be an effective strategy, but it can be easy to stop at JUST restating the question instead of offering a more specific, interesting introduction to your paper. The professor or teaching assistant wrote your question and will be reading many essays in response to it—they do not need to read a whole paragraph that simply restates the question.

Example: The Narrative of the Life of Frederick Douglass discusses the relationship between education and slavery in 19th century America, showing how white control of education reinforced slavery and how Douglass and other enslaved African Americans viewed education while they endured. Moreover, the book discusses the role that education played in the acquisition of freedom. Education was a major force for social change with regard to slavery.

3. The Webster’s Dictionary introduction. This introduction begins by giving the dictionary definition of one or more of the words in the assigned question. Anyone can look a word up in the dictionary and copy down what Webster says. If you want to open with a discussion of an important term, it may be far more interesting for you (and your reader) if you develop your own definition of the term in the specific context of your class and assignment. You may also be able to use a definition from one of the sources you’ve been reading for class. Also recognize that the dictionary is also not a particularly authoritative work—it doesn’t take into account the context of your course and doesn’t offer particularly detailed information. If you feel that you must seek out an authority, try to find one that is very relevant and specific. Perhaps a quotation from a source reading might prove better? Dictionary introductions are also ineffective simply because they are so overused. Instructors may see a great many papers that begin in this way, greatly decreasing the dramatic impact that any one of those papers will have.

Example: Webster’s dictionary defines slavery as “the state of being a slave,” as “the practice of owning slaves,” and as “a condition of hard work and subjection.”

4. The “dawn of man” introduction. This kind of introduction generally makes broad, sweeping statements about the relevance of this topic since the beginning of time, throughout the world, etc. It is usually very general (similar to the placeholder introduction) and fails to connect to the thesis. It may employ cliches—the phrases “the dawn of man” and “throughout human history” are examples, and it’s hard to imagine a time when starting with one of these would work. Instructors often find them extremely annoying.

Example: Since the dawn of man, slavery has been a problem in human history.

5. The book report introduction. This introduction is what you had to do for your elementary school book reports. It gives the name and author of the book you are writing about, tells what the book is about, and offers other basic facts about the book. You might resort to this sort of introduction when you are trying to fill space because it’s a familiar, comfortable format. It is ineffective because it offers details that your reader probably already knows and that are irrelevant to the thesis.

Example: Frederick Douglass wrote his autobiography, Narrative of the Life of Frederick Douglass, An American Slave , in the 1840s. It was published in 1986 by Penguin Books. In it, he tells the story of his life.

And now for the conclusion…

Writing an effective introduction can be tough. Try playing around with several different options and choose the one that ends up sounding best to you!

Just as your introduction helps readers make the transition to your topic, your conclusion needs to help them return to their daily lives–but with a lasting sense of how what they have just read is useful or meaningful. Check out our handout on  conclusions for tips on ending your paper as effectively as you began it!
