How to Cite an Essay in MLA

The guidelines for citing an essay in MLA format are similar to those for citing a chapter in a book. Include the author of the essay, the title of the essay, the name of the collection if the essay belongs to one, the editor of the collection or other contributors, the publication information, and the page number(s).

APA In-Text Citations and Sample Essay 7th Edition

This handout focuses on how to format in-text citations in APA.

Proper citation of sources is a two-part process . You must first cite each source in the body of your essay; these citations within the essay are called in-text citations . You MUST cite all quoted, paraphrased, or summarized words, ideas, and facts from sources. Without in-text citations, you are technically in danger of plagiarism, even if you have listed your sources at the end of the essay.

In-text citations point the reader to the sources’ information on the references page. The in-text citation typically includes the author's last name and the year of publication. If you use a direct quote, the page number is also provided.

More information can be found on p. 253 of the 7th edition of the Publication Manual of the American Psychological Association.

Citation Rules

Direct quotation with the author named in the text.

Heinze and Lu (2017) stated, “The NFL shifted its responses to institutional change around concussions significantly as the field itself evolved” (p. 509).

Note: The year of publication is listed in parenthesis after the names of the authors, and the page number is listed in parenthesis at the end of the quote.

Direct Quotation without the Author Named in the Text

As the NFL developed as an organization, it “shifted its responses to institutional change around concussions significantly” (Heinze & Lu, 2017, p. 509).

Note: At the end of the quote, the names of the authors, year of publication, and page number are listed in parenthesis.

Paraphrase with 1-2 Authors

As the NFL developed as an organization, its reactions toward concussions also transformed (Heinze & Lu, 2017).

Note: For paraphrases, page numbers are encouraged but not required.

Paraphrase with 3 or More Authors

To work toward solving the issue of violence in prisons begins with determining aspects that might connect with prisoners' violent conduct (Thomson et al., 2019).

Direct Quotation without an Author

The findings were astonishing "in a recent study of parent and adult child relationships" ("Parents and Their Children," 2007, p. 2).

Note: Since the author of the text is not stated, a shortened version of the title is used instead.

Secondary Sources

When using secondary sources, use the phrase "as cited in" and cite the secondary source on the References page.

In 1936, Keynes said, “governments should run deficits when the economy is slow to avoid unemployment” (as cited in Richardson, 2008, p. 257).

Long (Block) Quotations

When using direct quotations of 40 or more words, indent five spaces from the left margin without using quotation marks. The final period should come before the parenthetical citation.

At Meramec, an English department policy states:

To honor and protect their own work and that of others, all students must give credit to proprietary sources that are used for course work. It is assumed that any information that is not documented is either common knowledge in that field or the original work of that student. (St. Louis Community College, 2001, p. 1)

Website Citations

If citing a specific web document without a page number, include the name of the author, date, title of the section, and paragraph number in parentheses:

In America, “Two out of five deaths among U.S. teens are the result of a motor vehicle crash” (National Center for Injury Prevention and Control, 2004, Overview section, para. 1).

Here is a print-friendly version of this content.

How to Write an Academic Essay with References and Citations

#scribendiinc

Written by  Scribendi

If you're wondering how to write an academic essay with references, look no further. In this article, we'll discuss how to use in-text citations and references, including how to cite a website, how to cite a book, and how to cite a Tweet, according to various style guides.

You might need to cite sources when writing a paper that references other sources. For example, when writing an essay, you may use information from other works, such as books, articles, or websites. You must then inform readers where this information came from. Failure to do so, even accidentally, is plagiarism—passing off another person's work as your own.

You can avoid plagiarism and show readers where to find information by using citations and references. 

Citations tell readers where a piece of information came from. They take the form of footnotes, endnotes, or parenthetical elements, depending on your style guide. In-text citations are usually placed at the end of a sentence containing the relevant information. 

A reference list , bibliography, or works cited list at the end of a text provides additional details about these cited sources. This list includes enough publication information allowing readers to look up these sources themselves.

Referencing is important for more than simply avoiding plagiarism. Referring to a trustworthy source shows that the information is reliable. Referring to reliable information can also support your major points and back up your argument. 

Learning how to write an academic essay with references and how to use in-text citations will allow you to cite authors who have made similar arguments. This helps show that your argument is objective and not entirely based on personal biases.

How Do You Determine Which Style Guide to Use?

Often, a professor will assign a style guide. The purpose of a style guide is to provide writers with formatting instructions. If your professor has not assigned a style guide, they should still be able to recommend one. 

If you are entirely free to choose, pick one that aligns with your field (for example, APA is frequently used for scientific writing). 

Some of the most common style guides are as follows:

AP style for journalism

Chicago style for publishing

APA style for scholarly writing (commonly used in scientific fields)

MLA style for scholarly citations (commonly used in English literature fields)

Some journals have their own style guides, so if you plan to publish, check which guide your target journal uses. You can do this by locating your target journal's website and searching for author guidelines.

How Do You Pick Your Sources?

When learning how to write an academic essay with references, you must identify reliable sources that support your argument. 

As you read, think critically and evaluate sources for:

Objectivity

Keep detailed notes on the sources so that you can easily find them again, if needed.

Tip: Record these notes in the format of your style guide—your reference list will then be ready to go.

How to Use In-Text Citations in MLA

An in-text citation in MLA includes the author's last name and the relevant page number:

How Do You Cite a Tweet in MLA ?

MLA uses the full text of a short Tweet (under 140 characters) as its title. Longer Tweets can be shortened using ellipses. 

MLA Tweet references should be formatted as follows:

@twitterhandle (Author Name). "Text of Tweet." Twitter, Date Month, Year, time of

publication, URL.

With information from an actual Tweet, this looks like:

How to  Cite a Paraphrase in MLA

You can cite a paraphrase in MLA exactly the same way as you would cite a direct quotation. 

Make sure to include the author's name (either in the text or in the parenthetical citation) and the relevant page number.

How to Use In-Text Citations in APA

In APA, in-text citations include the author's last name and the year of publication; a page number is included only if a direct quotation is used:

Michelle Levy and Tom Mole (Eds.), The Broadview Reader in Book History (pp. 375–

394). Broadview Press.

Knowing how to cite a book and how to cite a chapter in a book correctly will take you a long way in creating an effective reference list.

How to Cite a Paraphrase in APA

You can cite a paraphrase in APA the same way as you would cite a direct quotation, including the author's name and year of publication. 

In APA, you may also choose to pinpoint the page from which the information is taken.

Referencing is an essential part of academic integrity. Learning how to write an academic essay with references and how to use in-text citations shows readers that you did your research and helps them locate your sources.

Learning how to cite a website, how to cite a book, and how to cite a paraphrase can also help you avoid plagiarism —an academic offense with serious consequences for your education or professional reputation.

A Quick Guide to Referencing | Cite Your Sources Correctly

Referencing means acknowledging the sources you have used in your writing. Including references helps you support your claims and ensures that you avoid plagiarism .

There are many referencing styles, but they usually consist of two things:

• A citation wherever you refer to a source in your text.
• A reference list or bibliography at the end listing full details of all your sources.

The most common method of referencing in UK universities is Harvard style , which uses author-date citations in the text. Our free Harvard Reference Generator automatically creates accurate references in this style.

Instantly correct all language mistakes in your text

Be assured that you'll submit flawless writing. Upload your document to correct all your mistakes.

Table of contents

Referencing styles, citing your sources with in-text citations, creating your reference list or bibliography, harvard referencing examples, frequently asked questions about referencing.

Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.

The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.

Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.

Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.

Harvard Referencing Guide

Vancouver referencing, used in biomedicine and other sciences, uses reference numbers in the text corresponding to a numbered reference list at the end.

Vancouver Referencing Guide

APA referencing, used in the social and behavioural sciences, uses author–date in-text citations corresponding to an alphabetical reference list at the end.

APA Referencing Guide APA Reference Generator

MHRA referencing, used in the humanities, uses footnotes in the text with source information, in addition to an alphabetised bibliography at the end.

MHRA Referencing Guide

OSCOLA referencing, used in law, uses footnotes in the text with source information, and an alphabetical bibliography at the end in longer texts.

OSCOLA Referencing Guide

Prevent plagiarism, run a free check.

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).

Quoting and paraphrasing

Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.

Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.

In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.

In-text citations

In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.

Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘

The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.

Placement of in-text citations

In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.

If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.

• Another researcher warns that the results of this method are ‘inconsistent’ (Singh, 2018, p. 13) .
• Previous research has frequently illustrated the pitfalls of this method (Singh, 2018; Jones, 2016) .
• Singh (2018, p. 13) warns that the results of this method are ‘inconsistent’.

The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.

A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.

Format of the reference list

Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.

Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.

Below are some examples of reference list entries for common source types in Harvard style.

• Chapter of a book
• Journal article

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:

• Harvard referencing , the most commonly used style in UK universities.
• MHRA , used in humanities subjects.
• APA , used in the social sciences.
• Vancouver , used in biomedicine.
• OSCOLA , used in law.

Your university may have its own referencing style guide.

If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.

References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.

If you don’t acknowledge your sources, you can get in trouble for plagiarism .

To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.

You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

Reference Examples

More than 100 reference examples and their corresponding in-text citations are presented in the seventh edition Publication Manual . Examples of the most common works that writers cite are provided on this page; additional examples are available in the Publication Manual .

To find the reference example you need, first select a category (e.g., periodicals) and then choose the appropriate type of work (e.g., journal article ) and follow the relevant example.

When selecting a category, use the webpages and websites category only when a work does not fit better within another category. For example, a report from a government website would use the reports category, whereas a page on a government website that is not a report or other work would use the webpages and websites category.

Also note that print and electronic references are largely the same. For example, to cite both print books and ebooks, use the books and reference works category and then choose the appropriate type of work (i.e., book ) and follow the relevant example (e.g., whole authored book ).

Examples on these pages illustrate the details of reference formats. We make every attempt to show examples that are in keeping with APA Style’s guiding principles of inclusivity and bias-free language. These examples are presented out of context only to demonstrate formatting issues (e.g., which elements to italicize, where punctuation is needed, placement of parentheses). References, including these examples, are not inherently endorsements for the ideas or content of the works themselves. An author may cite a work to support a statement or an idea, to critique that work, or for many other reasons. For more examples, see our sample papers .

What is APA Style?

APA style was created by social and behavioral scientists to standardize scientific writing. APA style is most often used in:

• psychology,
• social sciences (sociology, business), and

If you're taking courses in any of these areas, be prepared to use APA style.

For in-depth guidance on using this citation style, refer to Publication Manual of the American Psychological Association , 7th ed. We have several copies available at the MJC Library at the call number  BF 76.7 .P83 2020 .

APA Style, 7th ed.

In October 2019, the American Psychological Association made radical changes its style, especially with regard to the format and citation rules for students writing academic papers. Use this guide to learn how to format and cite your papers using APA Style, 7th edition.

You can start by viewing the  video tutorial .

For help on all aspects of formatting your paper in APA Style, see   The Essentials  page on the APA Style website.

• sans serif fonts such as 11-point Calibri, 11-point Arial, or 10-point Lucida Sans Unicode, or
• serif fonts such as 12-point Times New Roman, 11-point Georgia, or normal (10-point) Computer Modern (the default font for LaTeX)
• There are exceptions for the  title page ,  tables ,  figures ,  footnotes , and  displayed equations .
• Margins :  Use 1-in. margins on every side of the page.
• Align the text of an APA Style  paper to the left margin . Leave the right margin uneven, or “ragged.”
• Do not use full justification for student papers.
• Do not insert hyphens (manual breaks) in words at the end of line. However, it is acceptable if your word-processing program automatically inserts breaks in long hyperlinks (such as in a DOI or URL in a reference list entry).
• Indent the first line of each paragraph of text 0.5 in . from the left margin. Use the tab key or the automatic paragraph-formatting function of your word-processing program to achieve the indentation (the default setting is likely already 0.5 in.). Do not use the space bar to create indentation. 
• There are exceptions for the  title page ,  section labels ,  abstract ,  block quotations ,  headings ,  tables and figures ,  reference list , and  appendices .

Paper Elements

Student papers generally include, at a minimum: 

• Title Page (2.3)
• Text (2.11)
• References  (2.12)

Student papers may include additional elements such as tables and figures depending on the assignment. So, please check with your teacher!

Student papers generally  DO NOT  include the following unless your teacher specifically requests it:

• Running head
• Author note

For complete information on the  order of pages , see the APA Style website.

Number your pages consecutively starting with page 1. Each section begins on a new page. Put the pages in the following order:

• Page 1: Title page
• Page 2: Abstract (if your teacher requires an abstract)
• Page 3: Text 
• References begin on a new page after the last page of text
• Footnotes begin on a new page after the references (if your teacher requires footnotes)
• Tables begin each on a new page after the footnotes (if your teacher requires tables) 
• Figures begin on a new page after the tables (if your teacher requires figures)
• Appendices begin on a new page after the tables and/or figures (if your teacher requires appendices)

Sample Papers With Built-In Instructions

To see what your paper should look like, check out these sample papers with built-in instructions.

APA Style uses five (5) levels of headings to help you organize your paper and allow your audience to identify its key points easily. Levels of headings establish the hierarchy of your sections just like you did in your paper outline.

APA tells us to use "only the number of headings necessary to differentiate distinct section in your paper." Therefore, the number of heading levels you create depends on the length and complexity of your paper.

See the chart below for instructions on formatting your headings:

Use Word to Format Your Paper:

Use Google Docs to Format Your Paper:

Placement:  The reference list  appears at the end of the paper, on its own page(s). If your research paper ends on page 8, your References begin on page 9.

Heading:  Place the section label References  in bold at the top of the page, centered.

Arrangement:  Alphabetize entries by author's last name. If source has no named author, alphabetize by the title, ignoring A, An, or The. (9.44-9.48)

Spacing:  Like the rest of the APA paper, the reference list is double-spaced throughout. Be sure NOT to add extra spaces between citations.

Indentation:  To make citations easier to scan, add a  hanging indent  of 0.5 in. to any citation that runs more than one line. Use the paragraph-formatting function of your word processing program to create your hanging indent.  

See Sample References Page (from APA Sample Student Paper):

Elements of Reference List Entries: (Chapter 9)

References generally have four elements, each of which has a corresponding question for you to answer:

• Author:   Who is responsible for this work? (9.7-9.12)
• Date:   When was this work published? (9.13-9.17)
• Title:   What is this work called? (9.18-9.22)
• Source:   Where can I retrieve this work? (9.23-9.37)

By using these four elements and answering these four questions, you should be able to create a citation for any type of source.

For complete information on all of these elements, checkout the APA Style website.

This infographic shows the first page of a journal article. The locations of the reference elements are highlighted with different colors and callouts, and the same colors are used in the reference list entry to show how the entry corresponds to the source.

To create your references, you'll simple look for these elements in your source and put them together in your reference list entry.

Sometimes you won't be able to find all the elements required for your reference. In that case, see the  instructions in Table 9.1 of the APA style manual in section 9.4 or the APA Style website below:

• Direct Quotation of Material Without Page Numbers

The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.

• A  DOI  is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works.
• A  URL  specifies the location of digital information on the internet and can be found in the address bar of your internet browser. URLs in references should link directly to the cited work when possible.

When to Include DOIs and URLs:

• Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
• If an online work has both a DOI and a URL, include only the DOI.
• For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
• For works without DOIs from most academic research databases, do not include a URL or database information in the reference because these works are widely available. The reference should be the same as the reference for a print version of the work.
• For works from databases that publish original, proprietary material available only in that database (such as the UpToDate database) or for works of limited circulation in databases (such as monographs in the ERIC database), include the name of the database or archive and the URL of the work. If the URL requires a login or is session-specific (meaning it will not resolve for readers), provide the URL of the database or archive home page or login page instead of the URL for the work. (See APA Section 9.30 for more information). 
• If the URL is no longer working or no longer provides readers access to the content you intend to cite, try to find an archived version using the Internet Archive , then use the archived URL. If there is no archived URL, do not use that resource.

Format of DOIs and URLs:

Your DOI should look like this: 

https://doi.org/10.1037/a0040251

Follow these guidelines from the APA Style website.

APA Style uses the  author–date citation system , in which a brief in-text citation points your reader to the full reference list entry at the end of your paper. The in-text citation appears within the body of the paper and briefly identifies the cited work by its author and date of publication. This method enables your reader to locate the corresponding entry in the alphabetical reference list at the end of your paper.

Each work you cite  must  appear in the reference list, and each work in the reference list must be cited in the text (or in a table, figure, footnote, or appendix) except for the following (See APA, 8.4):

• Personal communications (8.9)
• General mentions of entire websites, whole periodicals (8.22), and common software and apps (10.10) in the text do not require a citation or reference list entry.
• The source of an epigraph does not usually appear in the reference list (8.35)
• Quotations from your research participants do not need citations or reference list entries (8.36)
• References included in a statistical meta-analysis, which are marked with an asterisk in the reference list, may be cited in the text (or not) at the author’s discretion. This exception is relevant only to authors who are conducting a meta-analysis (9.52).

Formatting Your In-Text Citations

Parenthetical and Narrative Citations: ( See APA Section  8.11)

In APA style you use the author-date citation system for citing references within your paper. You incorporate these references using either a  parenthetical   or a  narrative  style.

Parenthetical Citations

• In parenthetical citations, the author name and publication date appear in parentheses, separated by a comma. (Jones, 2018)
• A parenthetical citation can appear within or at the end of a sentence.
• When the parenthetical citation is at the end of the sentence, put the period or other end punctuation after the closing parenthesis.
• If there is no author, use the first few words of the reference list entry, usually the "Title" of the source: ("Autism," 2008) See APA 8.14
• When quoting, always provide the author, year, and specific page citation or paragraph number for nonpaginated materials in the text (Santa Barbara, 2010, p. 243).  See APA 8.13
• For most citations, the parenthetical reference is placed BEFORE the punctuation: Magnesium can be effective in treating PMS (Haggerty, 2012).

Narrative Citations 

In narrative citations, the author name or title of your source appears within your text and the publication date appears in parentheses immediately after the author name. 

• Santa Barbara (2010) noted a decline in the approval of disciplinary spanking of 26 percentage points from 1968 to 1994.

Using Sources Correctly

Crediting and Citing Your Sources

Now that you’ve just summarized or paraphrased or directly quoted a source, is there anything else you need to do with that source? Well, it turns out there is. There are some standard ways of using sources that let your readers know this material is from other texts rather than original ideas from your own brain. Following these guidelines also allows us, your readers, to locate those sources if we are interested in the topic and would like to know more about what they say.

 . . . . . . . . . . . . . . .

Giving credit to the sources you used creating a text is important (and useful!) for several reasons.

• It adds to your own credibility as an author by showing you have done appropriate research on your topic and approached your work ethically.
• It gives credit to the original author and their work for the ideas you found to be useful, and in giving them credit it helps you avoid unintentionally plagiarizing their work.
• It gives your readers additional resources (already curated by you in your research process!) that they can go to if they want to read further your topic.

What Does It Mean to Credit or Cite Your Sources?

For college-level work, this generally means two things: in-text or parenthetical citation and a “Works Cited” or “References” page. What these two things look like will be a little different for different types of classes (for example, it’s likely your writing class will use MLA—Modern Language Association—format, while a psychology class is more likely to use APA—American Psychological Association—format). The specific details required and the order in which they appear changes a little between different formats, but practicing one of them will give you a general idea of what most of them are looking for. All of the information we are looking at here is specific to MLA, which is the format you will use for your writing classes (and some other humanities classes).

Citing: Identifying In-Text Sources

Once you have brought source material into your writing (via quotation, summary, or paraphrase), your next task is to cite or identify it. This is essential because giving credit to the creator of the source material helps you avoid plagiarism. Identifying your sources also helps your reader understand which written content is from a source and which represents your ideas.

When you cite or identify source materials, you make it absolutely clear that the material was taken from a source. Note that if you don’t do that, your reader is left to assume the words are yours—and since that isn’t true, you will have committed plagiarism.

In-Text Citation

Every time you use an idea or language from a source in your text (so every time you summarize, paraphrase, or directly quote material from a source), you will want to add an in-text citation. Sometimes you can accomplish this simply by mentioning the author or title of a source in the body of your writing, but other times you’ll handle in-text citation differently, with a parenthetical citation. Parenthetical means that the citation appears in parentheses in the text of your essay.

A starting point for parenthetical citations is that they include the author’s last name and the page number where the borrowed information came from. For example, let’s say I’m using material from an article written by Lisa Smith. It’s in a physical magazine and spans pages 38-42. If, on page 41, she says something like, “While most studies have shown that Expo dry erase markers have superior lasting power, erasability, and color saturation than other brands on the market, their higher cost is a concern for some consumers,” I might incorporate that into a paper like this:

By most measurable standards, Expo markers are clearly the favored option (Smith 41).

However, you don’t always need both components (last name and page number) in the parenthetical citation. If I introduced the source material in the sentence above a little differently, introducing the author before delivering the material, I wouldn’t need to repeat the author’s name in that same sentence in the parenthetical citation. In that case, my sentence would look something like this: According to Lisa Smith, Expo markers are clearly the favored option by most measurable standards (41).

In this section, we’ll discuss three ways to cite or identify written source materials in your own writing.

1. Introduce the Author and/or the Title of the Source

By introducing the author or the material, you make it clear to the reader that what you’re talking about is from a source. Here’s an example of a quotation that is identified by introducing the author and the title of source (which are highlighted):

In the article, “Grooming Poodles for Fun and Profit,” Jonas Fogbottom explains , “Poodle grooming is a labor of love. It takes years of practice to be good at it, but once learned, it’s a fun and worthwhile career.”

Here’s an example of a paraphrase that is identified in the same way:

In the article, “Grooming Poodles for Fun and Profit,” Jonas Fogbottom says that although it takes a long time to become a skilled poodle groomer, it’s well worth the effort and leads to a good career.

Note that, in the example above, (1) if there are no page numbers to cite and (2) if the name of the author is signaled in the phrase that introduces the bit of source material, then there is no need for the parenthetical citation. This is an example of a situation where mentioning the author by name is the only in-text citation you’ll need. And sometimes, if the name of the author is unknown, then you might just mention the title of the article instead. It will be up to you, as a writer, to choose which method works best for your given situation.

The first time that you mention a source in your writing, you should always introduce the speaker and, if possible, the title of the source as well. Note that the speaker is the person responsible for stating the information that you’re citing and that this is not always the author of the text. For example, an author of an article might quote someone else, and you might quote or paraphrase that person.

Use the speaker’s full name (e.g. “According to Jonas Fogbottom . . .”) the first time you introduce them; if you mention them again in the paper, use their last name only (e.g. “Fogbottom goes on to discuss . . .”).

2. Use Linking or Attributive Language

Using linking language (sometimes called attributive language or signal phrases) simply means using words that show the reader you are still talking about a source that you just mentioned.

For example, you might use linking language that looks something like this:

• The author also explains . . .
• Fogbottom continues . . .
• The article goes on to say . . .
• The data set also demonstrates . . .

By using this kind of language, you make it clear to the reader that you’re still talking about a source. And while you’ll use this type of language throughout any researched essay whether you’re also using parenthetical citations or not, as we mentioned above, sometimes this linking language will be all you need for in-text citation.

Let’s look back at the last Fogbottom example from above, and imagine you wanted to add two more sentences from the same source. The linking language is highlighted :

In the article, “Grooming Poodles for Fun and Profit,” Jonas Fogbottom says that although it takes a long time to become a skilled poodle groomer, it’s well worth the effort and leads to a good career. Fogbottom goes on to explain how one is trained in the art of dog and poodle grooming. The article also gives a set of resources for people who want to know more about a dog grooming career.

Using the linking language makes it absolutely clear to your reader that you are still talking about a source.

3. Use a Parenthetical Citation

A parenthetical citation is a citation enclosed within parentheses.

The classic parenthetical citation includes the author’s name and, if there is one, a page number. To learn more about parenthetical citation and see some examples, see the Purdue OWL article on “ MLA In-Text Citations: The Basics ” (available from owl.english.purdue.edu).

Here’s an example :

(Fogbottom 16)

If there are two authors , list both (with a page number, if available):

(Smith and Jones 24)

If there are three or more authors , list the first author only and add “et al.”* (with a page number, if available):

(Smith et al. 62)

* et al means “and others.” If a text or source has three or more authors, MLA style has us just list the first one with et al .

But my source doesn’t have page numbers!

If you are using an electronic source or another kind of source with no page numbers, just leave the page number out:

(Fogbottom)

If you’re quoting or paraphrasing someone who was cited by the author of one of your sources , then that’s handled a bit differently. For example, what if you quote Smith, but you found that quote in the article by Fogbottom. In this case, you should introduce the speaker (Smith) as described above, and then cite the source for the quote, like this:

(qtd. in Fogbottom)

But my source doesn’t have an author!

This happens sometimes. Many useful documents, like government publications, organizational reports, and surveys, don’t list their authors. On the other hand, sometimes no clearly listed author can be a red flag that a source is not entirely trustworthy or is not researched well enough to be a reliable source for you.

If you encounter a source with no author, do look for other indicators that it is a good (or poor) source—who published it, does it have an appropriate list of references, is it current information, is it unbiased?

If you determine that this source is an appropriate source to use, then, when you create your in-text citation for it, you will simply use the title of the source (article, chapter, graph, film, etc.) in the place where you would have used the author’s name. If the title is long, you should abbreviate by listing the first one or two words of it (with a page number, if available).

Let’s imagine you’re working with a newspaper article entitled, “What’s New in Technology,” enclosed in quotation marks to indicate that this is an article title, and with no known author . Here’s what that would look in a parenthetical citation:

(“What’s New” B6)

If there is no author and you’re working with an electronic article, use the first one or two words in your parenthetical citation, again, enclosed in quotation marks. Let’s imagine you’re working with a web article entitled, “Pie Baking for Fun and Profit” and with no author. Here’s what that would look in a parenthetical citation:

(“Pie Baking”)

The parenthetical citation should be added at the end of the sentence that contains the source material. Let’s go back to the Fogbottom example and see how a parenthetical citation would work:

“Poodle grooming is a labor of love. It takes years of practice to be good at it, but once learned, it’s a fun and worthwhile career” (Fogbottom).

Here’s what it would look like if we used it with a paraphrase instead of a quotation:

Although it takes a long time to become a skilled poodle groomer, it’s well worth the effort and leads to a good career (Fogbottom).

Note that the citation is placed at the end of the sentence; the period comes after the parentheses. Misplacing the period is one of the most common formatting errors made by students.

Using parenthetical citation makes it crystal clear that a sentence comes from source material. This is, by far, the easiest way to cite or identify your source materials, too.

If using parenthetical citations is easy, why would we bother with using introduction or linking language to identify sources?

Good question! There would be nothing wrong with only using parenthetical citations all the way through your writing—it would absolutely do the job of citing the material. But, it wouldn’t read smoothly and would feel somewhat rough because every time a parenthetical citation popped up, the reader would be “stopped” in place for a moment. Using a combination of introduction, linking language, and parenthetical citation, as needed, makes the writing smoother and easier to read. It also integrates the source material with the writer’s ideas. We call this synthesis, and it’s part of the craft of writing.

Works Cited Entries

At the end of texts that have drawn from existing sources, you will often find a Works Cited page. This page gives more information than the parenthetical citations do about what kinds of sources were referenced in this work and where they can be found if the reader would like to know more about them. These entries all follow a specific and consistent format so that it is easy for readers to find the information they are looking for and so the shape and type of that information is consistent no matter who is writing the entries.

Until recently, the MLA required a slightly different format for every type of source—an entry for a Youtube video required certain information that was different from an entry for a book that was different from an entry for an online article. The most recent version of MLA, though—MLA 8—has simplified this so there is just one format rather than many.

You can learn how to create works cited entries in MLA 8 format, and see an example, in the “ Creating a Works Cited Page ” appendix to this text.

In-Text Citations

This in-text citation information will get you started, but see our full In-text Citation Guide for more information and additional examples .

• Basic Format

No Page Numbers

• 3 or More Authors

Basic Format: 1 Author and Page Numbers

Place the author’s last name and page number in parenthesis. If the in-text citation is at the end of a sentence, place the period outside the parenthesis.

Example 1:  (Hennessy 81).

Example 2:  (Hennessy 81-82).

If a source has no page numbers, omit the page number. Keep in mind, most electronic sources do not include pages.

Example 1: ("Everyday Victims")

Example 2: (Jones)

If the source has no author, your in-text citation will use the title of the source that starts your works cited entry. The title may appear in the sentence itself or, abbreviated, before the page number in parenthesis.

Example 1:  (“Noon” 508).

Example 2 :  ( Faulkner’s Novels  25).

Example 3 :  (“Climate Model Simulations").

If the entry on the Works Cited page begins with the names of two authors, include both last names in the in-text citation, connected by and.

Example:  (Dorris and Erdrich 23).

If the source has three or more authors, include the first author’s last name followed by et al.

Example:  (Burdick et al. 42).

Citation Styles Guide | Examples for All Major Styles

Published on June 24, 2022 by Jack Caulfield . Revised on November 7, 2022.

A citation style is a set of guidelines on how to cite sources in your academic writing . You always need a citation whenever you quote , paraphrase , or summarize a source to avoid plagiarism . How you present these citations depends on the style you follow. Scribbr’s citation generator can help!

Different styles are set by different universities, academic associations, and publishers, often published in an official handbook with in-depth instructions and examples.

There are many different citation styles, but they typically use one of three basic approaches: parenthetical citations , numerical citations, or note citations.

Parenthetical citations

• Chicago (Turabian) author-date

CSE name-year

Numerical citations

CSE citation-name or citation-sequence

Note citations

• Chicago (Turabian) notes and bibliography

Table of contents

Types of citation: parenthetical, note, numerical, which citation style should i use, parenthetical citation styles, numerical citation styles, note citation styles, frequently asked questions about citation styles.

The clearest identifying characteristic of any citation style is how the citations in the text are presented. There are three main approaches:

• Parenthetical citations: You include identifying details of the source in parentheses in the text—usually the author’s last name and the publication date, plus a page number if relevant ( author-date ). Sometimes the publication date is omitted ( author-page ).
• Numerical citations: You include a number in brackets or in superscript, which corresponds to an entry in your numbered reference list.
• Note citations: You include a full citation in a footnote or endnote, which is indicated in the text with a superscript number or symbol.

Citation styles also differ in terms of how you format the reference list or bibliography entries themselves (e.g., capitalization, order of information, use of italics). And many style guides also provide guidance on more general issues like text formatting, punctuation, and numbers.

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

In most cases, your university, department, or instructor will tell you which citation style you need to follow in your writing. If you’re not sure, it’s best to consult your institution’s guidelines or ask someone. If you’re submitting to a journal, they will usually require a specific style.

Sometimes, the choice of citation style may be left up to you. In those cases, you can base your decision on which citation styles are commonly used in your field. Try reading other articles from your discipline to see how they cite their sources, or consult the table below.

The American Anthropological Association (AAA) recommends citing your sources using Chicago author-date style . AAA style doesn’t have its own separate rules. This style is used in the field of anthropology.

APA Style is defined by the 7th edition of the Publication Manual of the American Psychological Association . It was designed for use in psychology, but today it’s widely used across various disciplines, especially in the social sciences.

Generate accurate APA citations with Scribbr

The citation style of the American Political Science Association (APSA) is used mainly in the field of political science.

The citation style of the American Sociological Association (ASA) is used primarily in the discipline of sociology.

Chicago author-date

Chicago author-date style is one of the two citation styles presented in the Chicago Manual of Style (17th edition). It’s used mainly in the sciences and social sciences.

• Parenthetical citations : Including identifying details of the source in parentheses —usually the author’s last name and the publication date, plus a page number if available ( author-date ). The publication date is occasionally omitted ( author-page ).
• Numerical citations: Including a number in brackets or superscript, corresponding to an entry in your numbered reference list.
• Note citations: Including a full citation in a footnote or endnote , which is indicated in the text with a superscript number or symbol.

Check if your university or course guidelines specify which citation style to use. If the choice is left up to you, consider which style is most commonly used in your field.
