What is a Works Cited list?
MLA style requires you to include a list of all the works cited in your paper on a new page at the end of your paper. The entries in the list should be in alphabetical order by the author's last name or by the element that comes first in the citation. (If there is no author's name listed, you would begin with the title.) The entire list should be double-spaced.
For each of the entries in the list, every line after the first line should be indented one-half inch from the left margin. "Works Cited" should be centered at the top of the page. If you are only citing one source, the page heading should be “Work Cited” instead of “Works Cited.” You can see a sample Works Cited here .
Building your Works Cited list
MLA citations in the Works Cited list are based on what the Modern Language Association calls "core elements." The core elements appear in the order listed below, in a citation punctuated with the punctuation mark that follows the element. For some elements, the correct punctuation will be a period, and for other elements, the correct punctuation will be a comma. Since you can choose the core elements that are relevant to the source you are citing, this format should allow you to build your own citations when you are citing sources that are new or unusual.
The author you should list is the primary creator of the work—the writer, the artist, or organization that is credited with creating the source. You should list the author in this format: last name, first name. If there are two authors, you should use this format: last name, first name, and first name last name. For three or more authors, you should list the first author followed by et al. That format looks like this: last name, first name, et al.
If a source was created by an organization and no individual author is listed, you should list that organization as the author.
Title of source .
This is the book, article, or website, podcast, work of art, or any other source you are citing. If the source does not have a title, you can describe it. For example, if you are citing an email you received, you would use this format in the place of a title:
Email to the author.
Title of container ,
A container is what MLA calls the place where you found the source. It could be a book that an article appears in, a website that an image appears on, a television series from which you are citing an episode, etc. If you are citing a source that is not “contained” in another source—like a book or a film—you do not need to list a container. Some sources will be in more than one container. For example, if you are citing a television episode that aired on a streaming service, the show would be the first container and the streaming service would be the second container.
Contributor ,
Contributors include editors, translators, directors, illustrators, or anyone else that you want to credit. You generally credit other contributors when their contributions are important to the way you are using the source. You should always credit editors of editions and anthologies of a single author’s work or of a collection of works by more than one author.
If you are using a particular version of a source, such as an updated edition, you should indicate that in the citation.
If your source is one of several in a numbered series, you should indicate this. So, for example, you might be using “volume 2” of a source. You would indicate this by “vol. 2” in the citation.
Publisher ,
For books, you can identify the publisher on the title or copyright page. For web sites, you may find the publisher at the bottom of the home page or on an “About” page. You do not need to include the publisher if you are citing a periodical or a Web site with the same name as the publisher.
Publication date ,
Books and articles tend to have an easily identifiable publication date. But articles published on the web may have more than one date—one for the original publication and one for the date posted online. You should use the date that is most relevant to your work. If you consulted the online version, this is the relevant date for your Works Cited list. If you can’t find a publication date—some websites will not include this information, for example—then you should include a date of access. The date of access should appear at the end of your citation in the following format:
Accessed 14 Oct. 2022.
The location in a print source will be the page number or range of pages you consulted. This is where the text you are citing is located in the larger container. For online sources, the location is generally a DOI, permalink, or URL. This is where your readers can locate the same online source that you consulted. MLA specifies that, if possible, you should include the DOI. Television episodes would be located at a URL. A work of art could be located in the museum where you saw it or online.
Your citations can also include certain optional elements. You should include optional elements if you think those elements would provide useful information to your readers. Optional elements follow the source title if they provide information that is not about the source as a whole. Put them at the end of the entry if they provide information about the source as a whole. These elements include the following:
Date of original publication .
If you think it would be useful to a reader to know that the text you are citing was originally published in a different era, you can put this information right after the title of the source. For example, if you are citing The Federalist Papers , you would provide the publication date of the edition you consulted, but you could also provide the original publication date:
Hamilton, Alexander, et al., editors. The Federalist Papers . October 1787-May 1788. Oxford University Press, 2008.
City of publication .
You should only use this information if you are citing a book published before 1900 (when books were associated with cities of publication rather than with publishers) or a book that has been published in a different version by the publisher in another city (a British version of a novel, for example). In the first case, you would put this information in place of the publisher's name. In the second case, the city would go before the publisher.
Descriptive terms .
If you are citing a version of a work when there are multiple versions available at the same location, you should explain this by adding a term that will describe your version. For example, if you watched a video of a presidential debate that was posted to YouTube along with a transcript, and you are quoting from the transcript, you should add the word “Transcript” at the end of your citation.

Creating a Works Cited list using the ninth edition
MLA is a style of documentation that may be applied to many different types of writing. Since texts have become increasingly digital, and the same document may often be found in several different sources, following a set of rigid rules no longer suffices.
Thus, the current system is based on a few guiding principles, rather than an extensive list of specific rules. While the handbook still describes how to cite sources, it is organized according to the process of documentation, rather than by the sources themselves. This gives writers a flexible method that is near-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:
- Title of source.
- Title of container,
- Other contributors,
- Publication date,
Each element should be followed by the corresponding punctuation mark shown above. Earlier editions of the handbook included the place of publication and required different punctuation (such as journal editions in parentheses and colons after issue numbers) depending on the type of source. In the current version, punctuation is simpler (only commas and periods separate the elements), and information about the source is kept to the basics.
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.
Bhabha, Homi K. The Location of Culture. Routledge, 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.
An individual webpage should be in quotation marks. The name of the parent website, which MLA treats as a "container," should follow 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. The name of the album should then follow in italics:
Beyoncé. "Pray You Catch Me." Lemonade, Parkwood Entertainment, 2016, www.beyonce.com/album/lemonade-visual-album/.
*The MLA handbook recommends including URLs when citing online sources. For more information, see the “Optional Elements” section below.
Title of container
The eighth edition of the MLA handbook introduced what are referred to as "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.
Wise, DeWanda. “Why TV Shows Make Me Feel Less Alone.” NAMI, 31 May 2019, www.nami.org/Blogs/NAMI-Blog/May-2019/How-TV-Shows-Make-Me-Feel-Less-Alone . Accessed 3 June 2019.
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.
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.
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.
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.
Quintilian. Institutio Oratoria. Translated by H. E. Butler, vol. 2, Loeb-Harvard UP, 1980.
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, websites whose titles are the same name as their publisher, websites that make works available but do 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 writing. 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. Below is a general citation for this 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 .
You should be as specific as possible in identifying a work’s location.
An essay in a book or an article in a 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. Remove any "http://" or "https://" tag from the beginning of the 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.
When citing a physical object that you experienced firsthand, identify the place of location.
Matisse, Henri. The Swimming Pool. 1952, Museum of Modern Art, New York .
Optional elements
The ninth 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 optional elements that can be included in 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, the MLA Handbook recommends including a date of access 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.
As mentioned above, while the MLA handbook recommends including URLs when you cite online sources, you should always check with your instructor or editor and include URLs at their discretion.
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 previous (eighth) edition
Although the MLA handbook is currently in its ninth edition, some information about citing in the text using the older (eighth) edition is being retained. 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 Works Cited list. For the most part, an in-text citation is the author’s name and the page number (or just the page number, if the author is named in the sentence) in parentheses :
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. For example: (00:02:15-00:02:35).
Again, your goal is to attribute your source and provide a reference without interrupting your text. Your readers should be able to follow the flow of your argument without becoming distracted by extra information.
