In-Text Citation Guidelines

In MLA Style, in-text citation is done using parenthetical citations following the author-page method. This involves providing source information (author and page number) in parentheses whenever a sentence uses quotation or paraphrase. 

Guidelines:

  • Author's last name and a page number for quoted or paraphrased material must appear in the text of your paper
  • a corresponding reference entry should be included on your works cited page
  • The author's name may appear in the sentence itself or in parentheses at the end of the sentence 
  • Page numbers should always appear in parenthesis at the end of the sentence. 

Example 1: Author's name as part of parenthetical citation

The House of Usher brought a sense of "iciness, a sinking, a sickening of the heart," over it's visitors (Poe 126). 

Example 2: Author's name used in sentence (Narrative Citation)

Gothic writers often describe settings to evoke emotion, and these settings often represent decay and ruin. This is evident in Poe's description of the House of Usher, "I looked upon the scene before me—upon the mere house, and simple landscape features of the domain—upon the bleak walls—upon the vacant eye-like windows—upon a few rank sedges—and upon a few white trunks of decayed trees” (126).

Works Cited Entry

Poe, Edgar Allen. "The Fall of the House of Usher." The Portable Edgar Allen Poe, edited by J. Gerald Kennedy, Penguin, 2006, pp.126-144.

An indirect quote is when you quote information that is cited in or quoted in another source--the source you are reading is not the original source of the content you wish to quote. As a general rule, you should try to avoid using indirect sources and find the original source if possible. Only use an indirect quote if you cannot locate the original source (for example, it is out of print) and the information you are quoting cannot be evidenced in some other way. 

Example of an indirect quote: 

Wolosky discusses the motivation of Dickinson's war poetry as seeking to justify the suffering of the war. In one of Dickinson's personal letters to her cousins, she writes, "I wish t'was plainer, the anguish in this world. I wish one could be sure the suffering had a loving side" (qtd. in Wolosky 111). 

Works Cited Entry

Wolosky, Shira. "Public and Private in Dickinson's War Poetry." A Historical Guide to Emily Dickinson, edited by Vivian R. Pollak, 2004, Oxford University Press, pp. 103-131. 

About the example:

Although we are quoting Dickinson's words we are not looking at the original source of those words. All we have in front of us is the secondary source, Wolosky's chapter about Dickinson, where she cites one of Dickinson's letters. The parenthetical citation and works cited entry included with the indirect quote therefore directs us to Wolosky's chapter since that is the source we are working with. 

Changes to quotations are made by adding or omitting words from the original quotation. 

Adding words

If you add words in a quotation you should put brackets around the words to indicate that they are not part of the original text. 

Example: adding words

Jan Harold Brunvand, in an essay on urban legends, states, "some individuals [who retell urban legends] make a point of learning every rumor or tale" (78).

Omitting words

If you omit words from a quotation, you should indicate the deleted word(s) by using ellipses, which are three periods preceded and followed by a space ( . . . )

Example: omitting words

In an essay on urban legends, Jan Harold Brunvand notes that "some individuals make a point of learning every recent rumor or tale . . . and in a short time a lively exchange of details occurs" (78).

Page Numbers

When you cite pages from a paginated work (a source that has assigned page numbers), always use the same style of numeral as the original source. 

Example: 1, 2, 3, 4 ... or i, ii, iii, iv ....

If a work is only one page long, do not give the page number in your in-text citation. 

If a quotation spans more than one page (i.e., starts at the bottom of one page and finishes at the top of the next page), include the page span in your in-text citation.

Example: (Harrison 6-7)

Paragraph Numbers

If your source uses explicit paragraph, section, chapter, or line numbers instead of page numbers, give the relevant numbers following the abbreviation "par." or "pars." You can also use labels like section (sec., secs.), chapters (ch., chs.), or lines (line, lines). Only use these labels if they are explicitly used by the original source - do not assign them yourself. 

Example: par. 10

If your source does not assign paragraph numbers, do not number them yourself. Omit the page number element from the in-text and works cited page citation. 

For additional information and examples on:

  • In-text citations for print sources with known author
  • In-text citations for print sources by corporate author
  • In-text citations for sources with non-standard labeling systems
  • In-text citations for print sources with no known author
  • Author-page citation for classic and literary works with multiple editions
  • Author-page citation of works in an anthology, periodical, or collection
  • Citing authors with same last names
  • Citing a work by multiple authors
  • Citing multiple works by the same author
  • Citing multi-volume works
  • Citing the bible
  • Citing transcripts, plays, or screenplays
  • Citing non-print sources from the internet
  • Miscellaneous non-print sources
  • Electronic sources
  • Multiple citations
  • Time-based media sources
  • When a citation is not needed

Citing with Missing Information

If you cannot identify an author, start the citation with the title of the source you are citing. 

Note: In cases of no author in a page on a website, list the organization responsible for the site as the author (this is called a group author). 

If the author is listed as "anonymous," use anonymous as the author. Do not list anonymous if the source simply has no author listed. 


Example: Page on Website, No Individual Author - Use Group Author

Group Author Name. "Title of webpage." Website Title, Date, URL. Accessed Day Month Year. 

American Heart Association. "What is a Heart Attack?" https://heart.org/en/health-topics/about-heart-attacks. Accessed 20 November 2024. 

In this citation, there are a couple of things happening. 

  • Group Author- American Heart Association
  • No date
  • Since the group author name and the website name are the same, you omit the website name to avoid repetition. 

Example: Online Article With No Individual or Group Author

"Tile of Article." Title of Website, publication date, URL. Accessed Day Month Year. 

"How to Call a Person Who Has Blocked Your Number." WikiHow, 3 September 2024, wikihow.com/call-a-person-that-has-blocked-your-number. Accessed 20 November 2024. 

Parenthetical citation: ("how to call")

If a source has no identifiable date, skip over the date element. Do not use a copyright date from the bottom of a website, as that applies to the whole website, not just the individual page. 

If the source has no identifiable page numbers, skip over the page number element in the citation. Do not assign page or paragraph numbers to sources that do not have any.

It is common for the following source types to have no page numbers:

  • webpages on websites
  • whole websites 
  • HTML only academic journal content (no PDF available).

AI (Chat GPT)

The below description has been copied word-for-word from the MLA blog post "How do I cite generative AI in MLA Style?"

When using generative AI, you should: 

  • cite a generative AI tool whenever you paraphrase, quote, or incorporate into your own work any content (whether text, image, data, or other) that was created by it 
  • acknowledge all functional uses of the tool (like editing your prose or translating words) in a note, your text, or another suitable location 
  • take care to vet the secondary sources it cites

Using the MLA Template

Author

We do not recommend treating the AI tool as an author. This recommendation follows the policies developed by various publishers, including the MLA’s journal PMLA

Title of Source

Describe what was generated by the AI tool. This may involve including information about the prompt in the Title of Source element if you have not done so in the text. 

Title of Container

Use the Title of Container element to name the AI tool (e.g., ChatGPT).

Version

Name the version of the AI tool as specifically as possible. For example, the examples in this post were developed using ChatGPT 3.5, which assigns a specific date to the version, so the Version element shows this version date.

Publisher

Name the company that made the tool.

Date

Give the date the content was generated.

Location

Give the general URL for the tool

Example: Passage in Source

screenshot of generative AI question: describe the symbolism of the green light in the book The Great Gatsby by F. Scott Fitzgerald

Paraphrased in Your Prose

While the green light in The Great Gatsby might be said to chiefly symbolize four main things: optimism, the unattainability of the American dream, greed, and covetousness (“Describe the symbolism”), arguably the most important—the one that ties all four themes together—is greed.

Works-Cited-List Entry

“Describe the symbolism of the green light in the book The Great Gatsby by F. Scott Fitzgerald” prompt. ChatGPT, 13 Feb. version, OpenAI, 8 Mar. 2023, chat.openai.com/chat.

Example: Quoting Text

Chat GPT response to question, "in 200 words, describe the symbolism of the green light in The Great Gatsby"

Quoted in Your Prose

When asked to describe the symbolism of the green light in The Great GatsbyChatGPT provided a summary about optimism, the unattainability of the American dream, greed, and covetousness. However, when further prompted to cite the source on which that summary was based, it noted that it lacked “the ability to conduct research or cite sources independently” but that it could “provide a list of scholarly sources related to the symbolism of the green light in The Great Gatsby” (“In 200 words”).

Works-Cited-List Entry

“In 200 words, describe the symbolism of the green light in The Great Gatsby” follow-up prompt to list sources. ChatGPT, 13 Feb. version, OpenAI, 9 Mar. 2023, chat.openai.com/chat.

While we’ve provided fairly detailed descriptions of the prompts above, a more general one (e.g., Symbolism of the green light in The Great Gatsby prompt) could be used, since you are describing something that mimics a conversation, which could have various prompts along the way.
