MLA Handbook image

Recent changes to the Modern Language Association’s (MLA) citation format sought to update the style for more modern sources and the way they are delivered. Currently in its eighth edition, the MLA Style Guide serves as the most popular citation guide in academic work. Seeking to simplify the citation process, the MLA guide’s current system is based on a few principles, rather than an extensive list of specific rules. Universally applicable, once familiar with the method, it can be used to document any type of source, for any type of paper, in any field.

Using the idea of core elements, general pieces of information that MLA suggests including in each Works Cited entry, MLA provides the order in Figure 1 for a proper citation with punctuation.Note that in the list, #3 says “Title of container.” This is a new term for MLA in the 8th edition and only means the vehicle used to deliver the information. For example, if you are citing a chapter of a book, the chapter you cite is the Title of the Source and the title of the book is the Title of the Container. Another example of this is when you encounter a journal article. The Title of the Source is the article title while the Title of the Container is the journal’s title.

Creating a Works Cited list using the eighth edition

MLA has turned to a style of documentation that is based on a general method that may be applied to every possible source, to many different types of writing. But since texts have become increasingly mobile, and the same document may be found in several different sources, following a set of fixed rules is no longer sufficient.         

The current system is based on a few principles, rather than an extensive list of specific rules. While the handbook still gives examples of how to cite sources, it is organized according to the process of documentation, rather than by the sources themselves. This process teaches writers a flexible method that is universally applicable. Once you are familiar with the method, you can use it to document any type of source, for any type of paper, in any field.

Here is an overview of the process:

When deciding how to cite your source, start by consulting the list of core elements. These are the general pieces of information that MLA suggests including in each Works Cited entry. In your citation, the elements should be listed in the following order:

  1. Author.
  2. Title of source.
  3. Title of container,
  4. Other contributors,
  5. Version,
  6. Number,
  7. Publisher,
  8. Publication date,
  9. Location.

Each element should be followed by the punctuation mark shown here. Earlier editions of the handbook included the place of publication, and required punctuation such as journal editions in parentheses, and colons after issue numbers. In the current version, punctuation is simpler (just commas and periods separate the elements), and information about the source is kept to the basics.

Author

Begin the entry with the author’s last name, followed by a comma and the rest of the name, as presented in the work. End this element with a period.

Said, Edward W. Culture and Imperialism. Knopf, 1994.

Title of source

The title of the source should follow the author’s name. Depending upon the type of source, it should be listed in italics or quotation marks.

A book should be in italics:

Henley, Patricia. The Hummingbird House. MacMurray, 1999.  

A website should be in italics:

Lundman, Susan. "How to Make Vegetarian Chili." eHow, www.ehow.com/how_10727_make-vegetarian-chili.html.*

A periodical (journal, magazine, newspaper article) should be in quotation marks:

Bagchi, Alaknanda. "Conflicting Nationalisms: The Voice of the Subaltern in Mahasweta Devi's Bashai Tudu." Tulsa Studies in Women's Literature, vol. 15, no. 1, 1996, pp. 41-50.

A song or piece of music on an album should be in quotation marks:

Beyoncé. "Pray You Catch Me." Lemonade, Parkwood Entertainment, 2016, www.beyonce.com/album/lemonade-visual-album/.

*The eighth edition handbook recommends including URLs when citing online sources. For more information, see the “Optional Elements” section below.

Title of container

Unlike earlier versions, the eighth edition refers to containers, which are the larger wholes in which the source is located. For example, if you want to cite a poem that is listed in a collection of poems, the individual poem is the source, while the larger collection is the container. The title of the container is usually italicized and followed by a comma, since the information that follows next describes the container.

Kincaid, Jamaica. "Girl." The Vintage Book of Contemporary American Short Stories, edited by Tobias Wolff, Vintage, 1994, pp. 306-07.

The container may also be a television series, which is made up of episodes.

“94 Meetings.” Parks and Recreation, created by Greg Daniels and Michael Schur, performance by Amy Poehler, season 2, episode 21, Deedle-Dee Productions and Universal Media Studios, 2010.

The container may also be a website, which contains articles, postings, and other works.

Zinkievich, Craig. Interview by Gareth Von Kallenbach. Skewed & Reviewed, 27 Apr. 2009, www.arcgames.com/en/games/star-trek-online/news/detail/1056940-skewed-%2526-reviewed-interviews-craig. Accessed 15 Mar. 2009.

In some cases, a container might be within a larger container. You might have read a book of short stories on Google Books, or watched a television series on Netflix. You might have found the electronic version of a journal on JSTOR. It is important to cite these containers within containers so that your readers can find the exact source that you used.

“94 Meetings.” Parks and Recreation, season 2, episode 21, NBC, 29 Apr. 2010. Netflix, www.netflix.com/watch/70152031?trackId=200256157&tctx=0%2C20%2C0974d361-27cd-44de-9c2a-2d9d868b9f64-12120962.

Langhamer, Claire. “Love and Courtship in Mid-Twentieth-Century England.” Historical Journal, vol. 50, no. 1, 2007, pp. 173-96. ProQuest, doi:10.1017/S0018246X06005966. Accessed 27 May 2009.

Other contributors

In addition to the author, there may be other contributors to the source who should be credited, such as editors, illustrators, translators, etc. If their contributions are relevant to your research, or necessary to identify the source, include their names in your documentation.

Note: In the eighth edition, terms like editor, illustrator, translator, etc., are no longer abbreviated.

Foucault, Michel. Madness and Civilization: A History of Insanity in the Age of Reason. Translated by Richard Howard, Vintage-Random House, 1988.

Woolf, Virginia. Jacob’s Room. Annotated and with an introduction by Vara Neverow, Harcourt, Inc., 2008.

Version

If a source is listed as an edition or version of a work, include it in your citation.

The Bible. Authorized King James Version, Oxford UP, 1998.

Crowley, Sharon, and Debra Hawhee. Ancient Rhetorics for Contemporary Students. 3rd      ed., Pearson, 2004.

Number

If a source is part of a numbered sequence, such as a multi-volume book, or journal with both volume and issue numbers, those numbers must be listed in your citation.

Dolby, Nadine. “Research in Youth Culture and Policy: Current Conditions and Future Directions.” Social Work and Society: The International Online-Only Journal, vol. 6, no.2, 2008, www.socwork.net/sws/article/view/60/362. Accessed 20 May 2009

“94 Meetings.” Parks and Recreation, created by Greg Daniels and Michael      Schur,             performance by Amy Poehler, season 2, episode 21, Deedle-    Dee Productions and Universal Media Studios, 2010.

Quintilian. Institutio Oratoria. Translated by H. E. Butler, vol. 2, Loeb-Harvard UP, 1980.

Publisher

The publisher produces or distributes the source to the public. If there is more than one publisher, and they are all are relevant to your research, list them in your citation, separated by a forward slash (/).

Klee, Paul. Twittering Machine. 1922. Museum of Modern Art, New York. The Artchive,  www.artchive.com/artchive/K/klee/twittering_machine.jpg.html. Accessed May 2006.

Women's Health: Problems of the Digestive System. American College of Obstetricians and Gynecologists, 2006.

Daniels, Greg and Michael Schur, creators. Parks and Recreation. Deedle-Dee Productions and Universal Media Studios, 2015.

Note: the publisher’s name need not be included in the following sources: periodicals, works published by their author or editor, a Web cite whose title is the same name as its publisher, a Web cite that makes works available but does not actually publish them (such as YouTube, WordPress, or JSTOR).

Publication date

The same source may have been published on more than one date, such as an online version of an original source. For example, a television series might have aired on a broadcast network on one date, but released on Netflix on a different date. When the source has more than one date, it is sufficient to use the date that is most relevant to your use of it. If you’re unsure about which date to use, go with the date of the source’s original publication.

In the following example, Mutant Enemy is the primary production company, and “Hush” was released in 1999. This is the way to create a general citation for a television episode.

“Hush.” Buffy the Vampire Slayer, created by Joss Whedon, performance by Sarah Michelle Gellar, season 4, Mutant Enemy, 1999.

However, if you are discussing, for example, the historical context in which the episode originally aired, you should cite the full date. Because you are specifying the date of airing, you would then use WB Television Network (rather than Mutant Enemy), because it was the network (rather than the production company) that aired the episode on the date you’re citing.

“Hush.” Buffy the Vampire Slayer, created by Joss Whedon, performance by Sarah Michelle Gellar, season 4, episode 10, WB Television Network, 14 Dec. 1999.

Location

You should be as specific as possible in identifying a work’s location.

An essay in a book, or an article in journal should include page numbers.

Adiche, Chimamanda Ngozi. “On Monday of Last Week.” The Thing around Your Neck, Alfred A. Knopf, 2009, pp. 74-94.

The location of an online work should include a URL.

Wheelis, Mark. "Investigating Disease Outbreaks Under a Protocol to the Biological and Toxin Weapons Convention." Emerging Infectious Diseases, vol. 6, no. 6, 2000, pp. 595-600, wwwnc.cdc.gov/eid/article/6/6/00-0607_article. Accessed 8 Feb. 2009.

A physical object that you experienced firsthand should identify the place of location.

Matisse, Henri. The Swimming Pool. 1952, Museum of Modern Art, New York.

Optional elements

The eighth edition is designed to be as streamlined as possible. The author should include any information that helps readers easily identify the source, without including unnecessary information that may be distracting. The following is a list of select optional elements that should be part of a documented source at the writer’s discretion.

Date of original publication:

If a source has been published on more than one date, the writer may want to include both dates if it will provide the reader with necessary or helpful information.

Erdrich, Louise. Love Medicine. 1984. Perennial-Harper, 1993.

City of publication:

The seventh edition handbook required the city in which a publisher is located, but the eighth edition states that this is only necessary in particular instances, such as in a work published before 1900. Since pre-1900 works were usually associated with the city in which they were published, your documentation may substitute the city name for the publisher’s name.

Thoreau, Henry David. Excursions. Boston, 1863.

Date of access:

When you cite an online source, include the date on which you accessed the material, since an online work may change or move at any time.

Bernstein, Mark. "10 Tips on Writing the Living Web." A List Apart: For People Who Make Websites, 16 Aug. 2002, alistapart.com/article/writeliving. Accessed 4 May 2009.

URLs:

As mentioned above, while the eighth edition recommends including URLs when you cite online sources, you should always check with your instructor or editor and include URLs at their discretion.

DOIs:

A DOI, or digital object identifier, is a series of digits and letters that leads to the location of an online source. Articles in journals are often assigned DOIs to ensure that the source is locatable, even if the URL changes. If your source is listed with a DOI, use that instead of a URL.

Alonso, Alvaro, and Julio A. Camargo. "Toxicity of Nitrite to Three Species of Freshwater Invertebrates." Environmental Toxicology, vol. 21, no. 1, 3 Feb. 2006, pp. 90-94. Wiley Online Library, doi: 10.1002/tox.20155.

Creating in-text citations using the eighth edition

The in-text citation is a brief reference within your text that indicates the source you consulted. It should properly attribute any ideas, paraphrases, or direct quotations to your source, and should direct readers to the entry in the list of works cited. For the most part, an in-text citation is the author’s name and page number (or just the page number, if the author is named in the sentence) in parentheses:

Imperialism is “the practice, the theory, and the attitudes of a dominating metropolitan center ruling a distant territory.” (Said 9).

or

According to Edward W. Said, imperialism is defined by “the practice, the theory, and the attitudes of a dominating metropolitan center ruling a distant territory.” (9).
Work Cited
Said, Edward W. Culture and Imperialism. Knopf, 1994.

When creating in-text citations for media that has a runtime, such as a movie or podcast, include the range of hours, minutes and seconds you plan to reference, like so (00:02:15-00:02:35).

Again, your goal is to attribute your source and provide your reader with a reference without interrupting your text. Your readers should be able to follow the flow of your argument without becoming distracted by extra information.

Final thoughts about the eighth edition

The current MLA guidelines teach you a widely applicable skill. Once you become familiar with the core elements that should be included in each entry in the Works Cited list, you will be able to create documentation for any type of source. While the handbook still includes helpful examples that you may use as guidelines, you will not need to consult it every time you need to figure out how to cite a source you’ve never used before. If you include the core elements, in the proper order, using consistent punctuation, you will be fully equipped to create a list of works cited on your own.

Basic in-text citation rules

In MLA style, referring to the works of others in your text is done by using what is known as parenthetical citation. This method involves placing relevant source information in parentheses after a quote or a paraphrase.

General Guidelines

  • The source information required in a parenthetical citation depends (1.) upon the source medium (e.g. Print, Web, DVD) and (2.) upon the source’s entry on the Works Cited (bibliography) page.
  • Any source information that you provide in-text must correspond to the source information on the Works Cited page. More specifically, whatever signal word or phrase you provide to your readers in the text, must be the first thing that appears on the left-hand margin of the corresponding entry in the Works Cited List.

In-text citations: Author-page style

MLA format follows the author-page method of in-text citation. This means that the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and a complete reference should appear on your Works Cited page. The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence. For example:

Wordsworth stated that Romantic poetry was marked by a "spontaneous overflow of powerful feelings" (263).

Romantic poetry is characterized by the "spontaneous overflow of powerful feelings" (Wordsworth 263).
Wordsworth extensively explored the role of emotion in the creative process (263).

Both citations in the examples above, (263) and (Wordsworth 263), tell readers that the information in the sentence can be located on page 263 of a work by an author named Wordsworth. If readers want more information about this source, they can turn to the Works Cited page, where, under the name of Wordsworth, they would find the following information:

Wordsworth, William. Lyrical Ballads. London: Oxford UP, 1967. Print.

In-text citations for print sources with known author

For Print sources like books, magazines, scholarly journal articles, and newspapers, provide a signal word or phrase (usually the author’s last name) and a page number. If you provide the signal word/phrase in the sentence, you do not need to include it in the parenthetical citation.

Human beings have been described by Kenneth Burke as "symbol-using animals" (3).
Human beings have been described as "symbol-using animals" (Burke 3).

These examples must correspond to an entry that begins with Burke, which will be the first thing that appears on the left-hand margin of an entry in the Works Cited:

Burke, Kenneth. Language as Symbolic Action: Essays on Life, Literature, and Method. Berkeley: U of California P, 1966. Print.

In-text citations for print sources by a corporate author

When a source has a corporate author, it is acceptable to use the name of the corporation followed by the page number for the in-text citation. You should also use abbreviations (e.g., nat'l for national) where appropriate, so as to avoid interrupting the flow of reading with overly long parenthetical citations.

In-text citations for print sources with no known author

When a source has no known author, use a shortened title of the work instead of an author name. Place the title in quotation marks if it's a short work (such as an article) or italicize it if it's a longer work (e.g. plays, books, television shows, entire Web sites) and provide a page number.

We see so many global warming hotspots in North America likely because this region has "more readily accessible climatic data and more comprehensive programs to monitor and study environmental change . . ." ("Impact of Global Warming" 6).

In this example, since the reader does not know the author of the article, an abbreviated title of the article appears in the parenthetical citation which corresponds to the full name of the article which appears first at the left-hand margin of its respective entry in the Works Cited. Thus, the writer includes the title in quotation marks as the signal phrase in the parenthetical citation in order to lead the reader directly to the source on the Works Cited page. The Works Cited entry appears as follows:

"The Impact of Global Warming in North America." Global Warming: Early Signs. 1999. Web. 23 Mar. 2009.

We'll learn how to make a Works Cited page in a bit, but right now it's important to know that parenthetical citations and Works Cited pages allow readers to know which sources you consulted in writing your essay, so that they can either verify your interpretation of the sources or use them in their own scholarly work.

Author-page citation for classic and literary works with multiple editions

Page numbers are always required, but additional citation information can help literary scholars, who may have a different edition of a classic work like Marx and Engels's The Communist Manifesto. In such cases, give the page number of your edition (making sure the edition is listed in your Works Cited page, of course) followed by a semicolon, and then the appropriate abbreviations for volume (vol.), book (bk.), part (pt.), chapter (ch.), section (sec.), or paragraph (par.). For example:

Marx and Engels described human history as marked by class struggles (79; ch. 1).

Citing authors with same last names

Sometimes more information is necessary to identify the source from which a quotation is taken. For instance, if two or more authors have the same last name, provide both authors' first initials (or even the authors' full name if different authors share initials) in your citation. For example:

Although some medical ethicists claim that cloning will lead to designer children (R. Miller 12), others note that the advantages for medical research outweigh this consideration (A. Miller 46).

Citing a work by multiple authors

For a source with three or fewer authors, list the authors' last names in the text or in the parenthetical citation:

Smith, Yang, and Moore argue that tougher gun control is not needed in the United States (76).
The authors state "Tighter gun control in the United States erodes Second Amendment rights" (Smith, Yang, and Moore 76).

For a source with more than three authors, use the work's bibliographic information as a guide for your citation. Provide the first author's last name followed by et al. or list all the last names.

Jones et al. counter Smith, Yang, and Moore's argument by noting that the current spike in gun violence in America compels law makers to adjust gun laws (4).

Or

Legal experts counter Smith, Yang, and Moore's argument by noting that the current spike in gun violence in America compels law makers to adjust gun laws (Jones et al. 4).

Or

Jones, Driscoll, Ackerson, and Bell counter Smith, Yang, and Moore's argument by noting that the current spike in gun violence in America compels law makers to adjust gun laws (4).

Citing multiple works by the same author

If you cite more than one work by a particular author, include a shortened title for the particular work from which you are quoting to distinguish it from the others. Put short titles of books in italics and short titles of articles in quotation marks.

Citing two articles by the same author:

Lightenor has argued that computers are not useful tools for small children ("Too Soon" 38), though he has acknowledged elsewhere that early exposure to computer games does lead to better small motor skill development in a child's second and third year ("Hand-Eye Development" 17).

Citing two books by the same author:

Murray states that writing is "a process" that "varies with our thinking style" (Write to Learn 6). Additionally, Murray argues that the purpose of writing is to "carry ideas and information from the mind of one person into the mind of another" (A Writer Teaches Writing 3).

Additionally, if the author's name is not mentioned in the sentence, you would format your citation with the author's name followed by a comma, followed by a shortened title of the work, followed, when appropriate, by page numbers:

Visual studies, because it is such a new discipline, may be "too easy" (Elkins, "Visual Studies" 63).

Citing multivolume works

If you cite from different volumes of a multivolume work, always include the volume number followed by a colon. Put a space after the colon, then provide the page number(s). (If you only cite from one volume, provide only the page number in parentheses.)

. . . as Quintilian wrote in Institutio Oratoria (1: 14-17).

Citing the Bible

In your first parenthetical citation, you want to make clear which Bible you're using (and underline or italicize the title), as each version varies in its translation, followed by book (do not italicize or underline), chapter and verse. For example:

Ezekiel saw "what seemed to be four living creatures," each with faces of a man, a lion, an ox, and an eagle (New Jerusalem Bible, Ezek. 1.5-10).

If future references employ the same edition of the Bible you’re using, list only the book, chapter, and verse in the parenthetical citation.

Citing indirect sources

Sometimes you may have to use an indirect source. An indirect source is a source cited in another source. For such indirect quotations, use "qtd. in" to indicate the source you actually consulted. For example:

Ravitch argues that high schools are pressured to act as "social service centers, and they don't do that well" (qtd. in Weisman 259).

Note that, in most cases, a responsible researcher will attempt to find the original source, rather than citing an indirect source.

Citing non-print or sources from the Internet

With more and more scholarly work being posted on the Internet, you may have to cite research you have completed in virtual environments. While many sources on the Internet should not be used for scholarly work (reference the OWL's Evaluating Sources of Information resource), some Web sources are perfectly acceptable for research. When creating in-text citations for electronic, film, or Internet sources, remember that your citation must reference the source in your Works Cited.

Sometimes writers are confused with how to craft parenthetical citations for electronic sources because of the absence of page numbers, but often, these sorts of entries do not require any sort of parenthetical citation at all. For electronic and Internet sources, follow the following guidelines:

  • Include in the text the first item that appears in the Work Cited entry that corresponds to the citation (e.g. author name, article name, website name, film name).
  • You do not need to give paragraph numbers or page numbers based on your Web browser’s print preview function.
  • Unless you must list the Web site name in the signal phrase in order to get the reader to the appropriate entry, do not include URLs in-text. Only provide partial URLs such as when the name of the site includes, for example, a domain name, like CNN.com or Forbes.com as opposed to writing out http://www.cnn.com or http://www.forbes.com.

Miscellaneous non-print sources

Werner Herzog's Fitzcarraldo stars Herzog's long-time film partner, Klaus Kinski. During the shooting of Fitzcarraldo, Herzog and Kinski were often at odds, but their explosive relationship fostered a memorable and influential film.
During the presentation, Jane Yates stated that invention and pre-writing are areas of rhetoric that need more attention.

In the two examples above “Herzog” from the first entry and “Yates” from the second lead the reader to the first item each citation’s respective entry on the Works Cited page:

Herzog, Werner, dir. Fitzcarraldo. Perf. Klaus Kinski. Filmverlag der Autoren, 1982.

Yates, Jane. "Invention in Rhetoric and Composition." Gaps Addressed: Future Work in Rhetoric and Composition, CCCC, Palmer House Hilton, 2002.

Electronic sources

One online film critic stated that Fitzcarraldo "has become notorious for its near-failure and many obstacles" (Taylor, “Fitzcarraldo”).
The Purdue OWL is accessed by millions of users every year. Its "MLA Formatting and Style Guide" is one of the most popular resources (Russell et al.).

In the first example, the writer has chosen not to include the author name in-text; however, two entries from the same author appear in the Works Cited. Thus, the writer includes both the author’s last name and the article title in the parenthetical citation in order to lead the reader to the appropriate entry on the Works Cited page (see below). In the second example, “Russell et al.” in the parenthetical citation gives the reader an author name followed by the abbreviation “et al.,” meaning, “and others,” for the article “MLA Formatting and Style Guide.” Both corresponding Works Cited entries are as follows:

Taylor, Rumsey. "Fitzcarraldo." Slant, 13 Jun. 2003, www.slantmagazine.com/film/review/fitzcarraldo/.

Russell, Tony, et al. "MLA Formatting and Style Guide." The Purdue OWL, 2 Aug. 2016, owl.english.purdue.edu/owl/resource/747/01/.

Multiple citations

To cite multiple sources in the same parenthetical reference, separate the citations by a semi-colon:

. . . as has been discussed elsewhere (Burke 3; Dewey 21).

Time-based media sources

When creating in-text citations for media that has a runtime, such as a movie or podcast, include the range of hours, minutes and seconds you plan to reference, like so (00:02:15-00:02:35).

When a citation is not needed

Common sense and ethics should determine your need for documenting sources. You do not need to give sources for familiar proverbs, well-known quotations or common knowledge. Remember, this is a rhetorical choice, based on audience. If you're writing for an expert audience of a scholarly journal, for example, they'll have different expectations of what constitutes common knowledge.
