What is a literature review?

A literature review is a critical summary and analysis of current scholarship on a topic. The material may be empirical, theoretical, critical, analytical, or methodological in nature and the literature may include multimedia and web-based material along with the more traditional book, report and journal article formats.

Why is a literature review important?

Literature reviews are important because they:

• Build knowledge and identify research methodologies and seminal works in your field.
• Help focus and refine your research question by articulating the knowledge gap.
• Provide the intellectual context for your work and situate it within the field.
• Ensure you will not be replicating existing knowledge or reproducing technical errors.
• Identify other researchers in your field.
• Identify the distinctive contribution your research will make and to produce a rationale and justification for your study.
• Show how research findings are discussed and presented in your discipline area.

For each resource, ask these questions:

• Has the author clearly defined the problem/issue and has its significance been clearly established?
• Could the problem or topic have been approached more effectively from another perspective?
• What is the author's research orientation and theoretical framework?
• In a research study how sound are the basic components of the study designed? How accurate and valid are the measurements? Is the analysis of the data accurate and are the conclusions valid and logical?
• Who is the intended audience of the material?
• Is there an objective basis to the reasoning or is the author merely trying to prove their already held beliefs?
• How does the author structure the argument?
• In what ways does the item contribute to your understanding of the problem? What are the strengths and limitations?
• How does the item specifically relate to the research you are about to undertake?

Conducting literature reviews

How you approach doing a literature review, whether you need to write a literature review or conduct a systematic review , will be dictated by the type of research you are doing. Whichever method you use, when it comes to literature review writing, you need to think about several things:

• The purpose of the review.
• Where it will be placed in the thesis.
• What the scope and focus of the literature review will be.

Planning and writing the literature review

There are several steps to developing a literature review and they are not necessarily sequential.

• Identify: Formulate your research question to help frame and direct your reading. Compile a list of references and determine the most appropriate system with which to file them, see managing your references using EndNote .
• Document: Keep a record of literature relating to your topic and make sure you can retrieve it again if necessary. Note why you have chosen each piece while it is fresh in your memory.
• Ensure Relevance: Prioritise the literature you have identified and note its importance. Screen literature before downloading or printing to avoid being overwhelmed by volume of material retrieved.
• Retrieve: Make copies of the most important literature first.
• Revise: When taking notes ensure you reference articles accurately so you will be able to cite them if necessary.
• Plan: Having a sense of the overall review will make it easier to write. It can be useful to draw diagrams of how the literature fits together to provide you with the big picture.
• Begin Writing: Start with an introduction that details what you intend to cover, how it will be organised and boundaries such as what is outside scope. Then discuss the literature in a logical and coherent way, concluding with a paragraph that relates to your research project. Abide by the academic conventions of your subject field.

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.

• Quick Run-through
• 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.

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

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.

When you’ve finished writing and revising your literature review, don’t forget to proofread thoroughly before submitting. Not a language expert? Check out Scribbr’s professional proofreading services !

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 .

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.

➡️ How to write a literature review in 3 steps

➡️ How to write a literature review in 30 minutes or less

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 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.

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.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

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.

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:

Frequently asked questions

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.

Writing Literature Reviews

What is a literature review.

"A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period. A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information. It might give a new interpretation of old material or combine new with old interpretations. Or it might trace the intellectual progression of the field, including major debates. And depending on the situation, the literature review may evaluate the sources and advise the reader on the most pertinent or relevant." Source: The Writing Center at UNC-Chapel Hill. (2013).

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.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

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 .

Literature Reviews: Outline

What is an Outline?

A literature review outline is a sketch highlighting how you will convey information about your findings after evaluating and interpreting studies. In other words, it offers a rough overview of the sources you have analyzed in the paper. 

Think of a literature outline as a general skeleton of what your full review should look like including the specifics of each part. Its purpose is to assist you in developing ideas, performing research and presenting your findings logically. Specifically, a literary review outline helps you sum up the arguments that you want to emphasize or what you will talk about in your study.

• Literature Review Outline: Writing Approaches with Examples

Elements of Literature Review Outline

• Pick a topic
• Search the body of literature in Summon or the databases
• Create an outline structure
• Identify key topics and themes from literature abstracts, summaries, and discussions
• Create an outline for literature review

Five Options for Organizing Information

CHRONOLOGICAL (by date):  This is one of the most common ways, especially for topics that have been talked about for a long time and have changed over their history. Organize it in stages of how the topic has changed: the first definitions of it, then major time periods of change as researchers talked about it, then how it is thought about today.

BROAD-TO-SPECIFIC : Another approach is to start with a section on the general type of issue you're reviewing, then narrow down to increasingly specific issues in the literature until you reach the articles that are most specifically similar to your research question, thesis statement, hypothesis, or proposal. This can be a good way to introduce a lot of background and related facets of your topic when there is not much directly on your topic but you are tying together many related, broader articles.

MAJOR MODELS or MAJOR THEORIES : When there are multiple models or prominent theories, it is a good idea to outline the theories or models that are applied the most in your articles. That way you can group the articles you read by the theoretical framework that each prefers, to get a good overview of the prominent approaches to your concept.

PROMINENT AUTHORS : If a certain researcher started a field, and there are several famous people who developed it more, a good approach can be grouping the famous author/researchers and what each is known to have said about the topic. You can then organize other authors into groups by which famous authors' ideas they are following. With this organisation it can help to look at the citations your articles list in them, to see if there is one author that appears over and over.

CONTRASTING SCHOOLS OF THOUGHT : If you find a dominant argument comes up in your research, with researchers taking two sides and talking about how the other is wrong, you may want to group your literature review by those schools of thought and contrast the differences in their approaches and ideas.

How to Write a Literature Review Outline

The format of a literature review is very similar to that of an essay.  It has:

An Introduction An introduction hooks the reader and reels them in, providing an overview.  It introduces the research topic by briefly mentioning key concepts and describing the chosen perspective of the remainder of the literature review.  The introduction discusses the literature to be reviewed and hints at the overall concept to be conveyed.  It also addresses any debates or concerns coming up in the body of the work.

Body Headings, subheadings, and paragraphs detailing the argument are contained there.  It is where the argument is both made and supported.

Conclusion Key points are detailed and summarized.  This includes major arguments and disagreements, in-depth explanations of findings, gaps in the research that require additional research or further study, and the overall perspective of the issue.

Literature Review Outline Example

Note how the author did the following:

• Wrote the items in such a way each line can be turned into a Level 2 or Level 3 heading
• Did not use the article titles in the outline, but created themes
• Used more than one source, when similar authors said the same thing
• Moved logically from one topic to the next.  That's one of the reasons to write an outline.
• After an introduction and history, moved to possible causes for the problem, then moved to proven solutions to remediate the problem.

How to Write a Literature Review

• What Is a Literature Review

What Is the Literature

• Writing the Review

The "literature" that is reviewed is the collection of publications (academic journal articles, books, conference proceedings, association papers, dissertations, etc) written by scholars and researchers for scholars and researchers. The professional literature is one (very significant) source of information for researchers, typically referred to as the secondary literature, or secondary sources. To use it, it is useful to know how it is created and how to access it.

The "Information Cycle"

The diagram below is a brief general picture of how scholarly literature is produced and used. Research does not have a beginning or an end; researchers build on work that has already been done in order to add to it, thus providing more resources for other researchers to build on. They read the professional literature of their field to see what issues, questions, and problems are current, then formulate a plan to address one or a few of those issues. Then they make a more focused review of the literature, which they use to refine their research plan. After carrying out the research, they present their results (presentations at conferences, published articles, etc) to other scholars in the field, i.e. they add to the general subject reading ("the literature").

  Research may not have a beginning or an end, but researchers have to begin somewhere. As noted above, the professional literature is typically referred to as secondary sources. Primary and tertiary sources also play important roles in research. Note, though, that these labels are not rigid distinctions; the same resource can overlap categories.

• Lab reports (yours or someone else's) - Records of the results of experiments.
• Field notes, measurements, etc (yours or someone else's) - Records of observations of the natural world (electrons, elephants, earthquakes, etc).
• Journal articles, conference proceedings , and similar publications reporting results of original research.
• Historical documents - Official papers, maps, treaties, etc.
• Government publications - Census statistics, economic data, court reports, etc.
• Statistical data - Measurements (counts, surveys, etc.) compiled by researchers.
• First-person accounts - Diaries, memoirs, letters, interviews, speeches
• Newspapers - Some types of articles, e.g. stories on a breaking issue, or journalists reporting the results of their investigations.
• Published writings - Novels, stories, poems, essays, philosophical treatises, etc
• Works of art - Paintings, sculptures, etc.
• Recordings - audio, video, photographic
• Conference proceedings - Scholars and researchers getting together and presenting their latest ideas and findings
• Internet - Web sites that publish the author's findings or research; e.g. your professor's home page listing research results. Note: use extreme caution when using the Internet as a primary source … remember, anyone with internet access can post whatever they want.
• Archives - Records (minutes of meetings, purchase invoices, financial statements, etc.) of an organization (e.g. The Nature Conservancy), institution (e.g. Wesleyan University), business, or other group entity (even the Grateful Dead has an archivist on staff).
• Artifacts - manufactured items such as clothing, furniture, tools, buildings
• Manuscript collections - Collected writings, notes, letters, diaries, and other unpublished works.
• Books or articles - Depending on the purpose and perspective of your project, works intended as secondary sources -- analyzing or critiquing primary sources -- can serve as primary sources for your research.
• Secondary - Books, articles, and other writings by scholars and researchers reporting their analysis of their primary sources to others. They may be reporting the results of their own primary research or critiquing the work of others. As such, these sources are usually a major focus of a literature review: this is where you go to find out in detail what has been and is being done in a field, and thus to see how your work can contribute to the field.   
• Summaries / Introductions - Encyclopedias, dictionaries, textbooks, yearbooks, and other sources which provide an introductory or summary state of the art of the research in the subject areas covered. They are an efficient means to quickly build a general framework for understanding a field.
• Indexes to publications - Provide lists of primary and secondary sources of more extensive information. They are an efficient means of finding books, articles, conference proceedings, and other publications in which scholars report the results of their research.

Work backwards . Usually, your research should begin with tertiary sources:

• Tertiary - Start by finding background information on your topic by consulting reference sources for introductions and summaries, and to find bibliographies or citations of secondary and primary sources.
• Secondary - Find books, articles, and other sources providing more extensive and thorough analyses of a topic. Check to see what other scholars have to say about your topic, find out what has been done and where there is a need for further research, and discover appropriate methodologies for carrying out that research. 
• Primary - Now that you have a solid background knowledge of your topic and a plan for your own research, you are better able to understand, interpret, and analyze the primary source information. See if you can find primary source evidence to support or refute what other scholars have said about your topic, or posit an interpretation of your own and look for more primary sources or create more original data to confirm or refute your thesis. When you present your conclusions, you will have produced another secondary source to aid others in their research.

Publishing the Literature

There are a variety of avenues for scholars to report the results of their research, and each has a role to play in scholarly communication. Not all of these avenues result in official or easily findable publications, or even any publication at all. The categories of scholarly communication listed here are a general outline; keep in mind that they can vary in type and importance between disciplines.

Peer Review - An important part of academic publishing is the peer review, or refereeing,  process. When a scholar submits an article to an academic journal or a book manuscript to a university publisher, the editors or publishers will send copies to other scholars and experts in that field who will review it. The reviewers will check to make sure the author has used methodologies appropriate to the topic, used those methodologies properly, taken other relevant work into account, and adequately supported the conclusions, as well as consider the relevance and importance to the field. A submission may be rejected, or sent back for revisions before being accepted for publication.

Peer review does not guarantee that an article or book is 100% correct. Rather, it provides a "stamp of approval" saying that experts in the field have judged this to be a worthy contribution to the professional discussion of an academic field.

Peer reviewed journals typically note that they are peer reviewed, usually somewhere in the first few pages of each issue. Books published by university presses typically go through a similar review process. Other book publishers may also have a peer review process. But the quality of the reviewing can vary among different book or journal publishers. Use academic book reviews or check how often and in what sources articles in a journal are cited, or ask a professor or two in the field, to get an idea of the reliability and importance of different authors, journals, and publishers.

Informal Sharing - In person or online, researchers discuss their ongoing projects to let others know what they are up to or to give or receive assistance in their work. Conferences, listservs, and online discussion boards are common avenues for these discussions. Increasingly, scholars are using personal web sites to present their work.

Conference Presentations - Many academic organizations sponsor conferences at which scholars read papers, display at poster sessions, or otherwise present the results of their work. To give a presentation, scholars must submit a proposal which is reviewed by those sponsoring the conference. Unless a presentation is published in another venue, it will likely be difficult to find a copy, or even to know what was presented. Some subject specific indexes and other sources list conference proceedings along with the author and contact information.

Conference Papers / Association Papers / Working Papers - Papers presented at a conference, submitted but not yet accepted for publication, works in progress, or not otherwise published are sometimes made available by academic associations. These are often not easy to find, but many are indexed in subject specific indexes or available in subject databases. Sometimes a collection of papers presented at a conference will be published in a book.

Journals - Articles in journals contain specific analyses of particular aspects of a topic. Journal articles can be written and published more quickly than books, academic libraries subscribe to many journals, and the contents of these journals are indexed in a variety of sources so others can easily find them. So, researchers commonly use articles to report their findings to a wide audience, and journals are a good readily available source for anyone researching current information on a topic.

• Research journals - Articles reporting in detail the results of research.
• Review journals - Articles reviewing the literature and work done on particular topics.
• News/Letters journals - News reports, brief research reports, short discussions of current issues.
• Proceedings/Transactions journals - A common venue for publishing conference papers or other proceedings of academic conferences.
• General interest magazines - News and other magazines that report scholarly findings for a general, nonacademic audience. These are usually written by journalists (who are usually not academically trained in the field), but sometimes are written by researchers (or at least by journalists with training in the field). Magazines are not peer reviewed, and are usually not academically useful sources of information for research purposes, but they can alert you to work being done in your field and give you a quick summary.
• Trade journals and magazines - These are written for people working in a particular industry or profession, such as advertising, banking, construction, dentistry, education. Articles are generally written by and for people working in that trade, and focus on current topics and developments in the trade. They do not present academic analyses of their topics, but they can provide useful background or context for academic work if the articles are relevant to your research.

Books - Books take a longer time than articles or conference presentations to get from research to publication, but they can cover a broader range of topics, or cover a topic much more thoroughly. University press books typically go through some sort of a peer review process. There is a wide range of review processes (from rigorous to none at all) among other book publishers.

Dissertations/Theses - Graduate students working on advanced degrees typically must perform a substantial piece of original work, and then present the results in the form of a thesis or dissertation. A master's thesis is typically somewhere between an article and a book in length, and a doctoral dissertation is typically about the length of a book. Both should include extensive bibliographies of their topics. 

Web sites - In addition to researchers informally presenting and discussing their work on personal web pages, there are an increasing number of peer reviewed web sites publishing academic work. The rigor, and even existence, of peer reviewing can vary widely on the web, and it can be difficult to determine the reliability of information presented on the web, so always be careful in relying on a web-based information source. Do your own checking and reviewing to make sure the web site and the information it presents are reliable.

Reference Sources - Subject encyclopedias, dictionaries, and other reference sources present brief introductions to or summaries of the current work in a field or on a topic. These are typically produced by a scholar and/or publisher serving as an editor who invites submissions for articles from experts on the topics covered.

How to Find the Literature

Just as there are many avenues for the literature to be published and disseminated, there are many avenues for searching for and finding the literature. There are, for example, a variety of general and subject specific indexes which list citations to publications (books, articles, conference proceedings, dissertations, etc). The Wesleyan Library web site has links to the library catalog and many indexes and databases in which to search for resources, along with subject guides to list resources appropriate for specific academic disciplines. When you find some appropriate books, articles, etc, look in their bibliographies for other publications and also for other authors writing about the same topics. For research assistance tailored to your topic, you can sign up for a Personal Research Session with a librarian.

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 .

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.

What is Peer Review?

If an article is peer reviewed , it was reviewed by scholars who are experts in related academic or professional fields before it was published. Those scholars assessed the quality of the article's research, as well as its overall contribution to the literature in their field. 

When we talk about peer-reviewed journals , we're referring to journals that use a peer-review process.

Related terms you might hear include: 

• Academic: Intended for academic use, or an academic audience. 
• Scholarly:  Intended for scholarly use, or a scholarly audience. 
• Refereed: Refers to a specific kind of peer-review process.

How Do I Know If a Journal is Peer-Reviewed?

The easiest way to find out if a journal is peer-reviewed is to search for the title in a serials directory like UlrichsWeb:

• UlrichsWeb Global Serials Directory Includes in each record: ISBN, title, publisher, country of publication, status (Active, ceased, etc.), start year, frequency, refereed (Yes/No), media, language, price, subject, Dewey #, circulation, editor(s), email, URL, brief description Also known as: Ulrichs
• Type the name of the journal in the search bar and click the search button. NOTE: you need to use the full name of the journal, not an abbreviation.

• Locate the journal in the results list. You may see multiple entries for one journal because Ulrichs lists print, electronic, and international version separately.

How Do I Know If an Article is Peer-Reviewed?

Even if an article was published in a peer-reviewed journal, it may not necessarily be peer-reviewed itself; for example, a commentary article may undergo editorial review instead, meaning it was only reviewed by the journal editor.

There are some clues you can look for to help you identify if an article is peer-reviewed:

• Does the abstract discuss the author's/authors' research process?
• Does the abstract include a variation of the phrase "This study..."?
• Is there a Methodology or Data header in the text of the article?
• Does the paper discuss related research in a literature review?
• Is there an analysis of a need for further research, or gaps in the literature?
• Are the references for scholarly articles and books?

If an article published in a verified peer-reviewed journal includes these elements, it is most likely a peer-reviewed article.
