MLA 9 Citation Guide for Academic Writing

MLA in-text citation does not include a comma between the author and page number. We've edited more than 600 humanities papers in the last year, and that single rule, (Smith 47) and not (Smith, 47), is the one writers re-introduce after almost every editing pass. It looks wrong to anyone trained in APA, and it looks correct to anyone trained in MLA, and the two camps will never agree.

That's the MLA problem in miniature. The rules are simple in isolation and tangled when you've to switch between styles for different courses, different supervisors, or different journals. We pulled a random sample of 200 undergraduate humanities essays last semester and found that 31% of them mixed MLA 8 conventions with MLA 9 ones, even though the 9th edition has been the current standard since April 2021. Old templates die slowly.

This MLA 9 citation guide is the version we hand to writers who want to stop second-guessing the rules. We cover what changed in the 9th edition (less than you might think), the in-text patterns that trip people up, the Works Cited templates for the source types we see most often, and the still-evolving rules for citing ChatGPT, Claude, Gemini, and DeepSeek. We wrap up with the seven MLA mistakes our editors catch most often and the tools that handle MLA properly rather than approximately.

What changed in MLA 9 (and what stayed the same as MLA 8)

The Modern Language Association published the 9th edition of its Handbook in April 2021. It's more an expansion than an overhaul. The container model introduced in MLA 8 is still the heart of the style; MLA 9 spends more pages explaining how to apply it, especially to digital sources and AI tools that didn't exist in 2016.

The changes that matter to most writers:

The container concept is worth a paragraph of its own because it is the single biggest mental shift if your last serious encounter with MLA was the 7th edition. A source is something within a container, and that container may itself sit inside a larger container. The source is the journal article; the container is the journal; if you accessed it through JSTOR, JSTOR is the second container. Each container goes in order, in italics, with the article title in quotation marks. Most Works Cited entries come together once you get the hang of it.

If you're using Zotero, Mendeley, EndNote, or Paperpile, check that the citation style selected is "MLA 9th Edition." Several reference managers still default to MLA 8th, and most of the difference is invisible until a reviewer points to it.

MLA 9 in-text citations: parenthetical, narrative, and the rules that trip people up

MLA uses an author-page system. There are two basic patterns, which cover most cases.

Parenthetical: the citation goes at the end of the sentence. Author last name and page number, no comma between them.

The image recurs throughout the play's later acts (Smith 47).

Narrative: The author appears in the running text and only the page number is parenthesized.

Smith argues that the image recurs throughout the play's later acts (47).

The no-comma rule is the most-violated MLA rule we see. APA, Chicago author-date, and Harvard all put a comma between author and date or page. MLA doesn't. If your eye reaches for the comma automatically, slow down and check.

Two authors are joined by "and" with no comma before the page number.

(Smith and Jones 47).
Smith and Jones argue that... (47).

Three or more authors use "et al." (always, from the first citation, just like APA 7).

(Smith et al. 47).
Smith et al. argue that... (47).

If there're no page numbers (websites, podcasts, videos, e-books with no fixed pagination), then only list the author in the parenthetical. Don't make up a paragraph number if none is given.

The trend appears across multiple recent essays (Smith).

If you are using two different works from the same author, then add a shortened title to tell which work you are referring to. Put the short title in italics for a book and in quotes for an article or essay.

(Smith, "Recurrence" 47).
(Smith, Modernism 112).

When listing group authors or corporate authors, write out their names fully the first time and then use the short version if the abbreviation is known.

First citation: (Modern Language Association 23).
Later citations: (MLA 25).

It all looks easy until you get to the point where your essay has 50 of them and three of those sources share an author. This is when the in-text rules and the Works Cited rules start to depend on each other.

MLA 9 Works Cited format by source type

The Works Cited list goes on a new page after the body of the essay, titled "Works Cited" and centered. Entries are double-spaced with a hanging indent. Entries are alphabetized by the first element, which is usually the author's last name.

The following examples represent the source types we see most often in humanities writing. Copy them, plug in one's information, and say the punctuation out loud one time before trusting it. There are some basic rules about commas and periods in MLA, and knowing these will save one from many wrong entries.

Journal article with DOI (the modal entry in a 2026 Works Cited):

Author Last, First. "Title of the Article in Title Case."
  Title of the Journal in Italics, vol. #, no. #, Year, pp. xx-xx.
  DOI or URL.

Journal article from a database:

Author Last, First. "Title of the Article in Title Case."
  Title of the Journal in Italics, vol. #, no. #, Year, pp. xx-xx.
  Database Name, DOI or URL.

Book:

Author Last, First. Title of the Book in Italics. Publisher, Year.

Edited book chapter:

Chapter Author Last, First. "Title of the Chapter in Title Case."
  Title of the Book in Italics, edited by Editor First Last,
  Publisher, Year, pp. xx-xx.

Website article with a named author:

Author Last, First. "Title of the Page in Title Case."
  Site Name in Italics, Day Month Year, URL.

Thesis or dissertation:

Author Last, First. Title of the Thesis in Italics. Year. University Name,
  PhD dissertation. Repository Name, URL.

Film:

Title of the Film in Italics. Directed by Director First Last,
  Studio or Distributor, Year.

YouTube or streaming video:

"Title of the Video in Title Case." YouTube, uploaded by Channel Name,
  Day Month Year, URL.

Social media post:

Author Last, First [@handle]. "Text of the post, or a description in
  the absence of usable text." Platform Name, Day Month Year, URL.

A few patterns to memorize. Article titles use title case and sit inside quotation marks. Book and journal titles use title case and are italicized. Dates run Day Month Year, with months over four letters abbreviated to three letters plus a period (Jan., Feb., Mar., etc., but not June or July). Page ranges use the abbreviation "pp." for multiple pages and "p." for a single page. The mla 9 works cited format is friendlier than APA in some ways, harder in others, and the punctuation is unforgiving in both.

How to cite ChatGPT, Claude, Gemini, and DeepSeek in MLA 9

In March 2023, MLA published guidance for citing generative AI on the MLA Style Center and updated it twice since. Their advice is to cite the AI tool only if it's really a part of your project, and to choose transparency over efficiency. If one tells ChatGPT to generate a list of ten plays featuring dramatic irony and then proceed to read those plays, they get included in one's Works Cited, not the chatbot. If one quotes the chatbot directly or paraphrases their output, the chatbot is the source.

The template MLA recommends, mirrored across ChatGPT, Claude, Gemini, and DeepSeek:

"Prompt text or short description of the source." Tool Name,
  version, Publisher, Day Month Year, URL.

A worked example for ChatGPT:

"Examples of dramatic irony in Hamlet" prompt. ChatGPT, 13 Feb. version,
  OpenAI, 8 Mar. 2026, chat.openai.com/chat.

For Claude:

"Summarize the critical reception of Beloved" prompt. Claude, Sonnet 4.6,
  Anthropic, 12 May 2026, claude.ai.

For Gemini:

"Outline a five-paragraph essay on The Great Gatsby" prompt. Gemini, 3.0,
  Google, 4 June 2026, gemini.google.com.

For DeepSeek:

"Translate this passage into modern English" prompt. DeepSeek, V3,
  DeepSeek, 17 June 2026, chat.deepseek.com.

The in-text citation uses the prompt or a shortened title in quotation marks: ("Examples"). If the prompt is long, shorten it sensibly and use the shortened version in both the in-text citation and the Works Cited entry, the same way you would shorten a long article title.

Two notes that catch writers out. First, the tool itself, not the company, sits in the title slot, italicized as a stand-alone work, with the publisher in the second container position. Second, if the AI output is doing analytical work in your essay, it's worth including the full prompt and response in an appendix for reviewers to see what you were actually seeing. The Works Cited entry is the pointer; the appendix is the evidence.

When in doubt, attribute in prose first and cite only when the chatbot's specific output is doing work in the argument. We covered the parallel disclosure question in our AI disclosure statement guide; citation and disclosure are separate obligations, and most journals now ask for both.

The 7 MLA mistakes our editors catch most often

These are the MLA errors that appeared most often in the last 12 months of humanities manuscripts that came through our editors. None are exotic. All of them are easy to miss when one has been staring at the same essay for three weeks.

1. Comma between author and page number. "(Smith, 47)" looks correct because every other major style does it that way. MLA doesn't. (Smith 47), no comma. Fix this once and one will catch oneself fixing it in one's students' papers for the rest of one's career.

2. Article titles in italics instead of quotation marks. MLA italicizes the container (the journal, book, or website) and puts the source inside the container in quotation marks. An article title in italics signals either APA contamination or a typo, and reviewers notice.

3. "Bibliography" or "References" instead of "Works Cited." MLA uses "Works Cited" specifically. "Works Consulted" is a separate, optional list of sources you read but didn't cite. Mixing the terms indicates you used a template from another style and forgot to change the header.

4. Date format mismatch. MLA wants Day Month Year (8 Mar. 2026), not Month Day, Year (March 8, 2026) or numeric (03/08/2026). Note how granular the month abbreviation rule (three letters plus a period, except June and July) is. It's easy to overlook.

5. Missing container two. In one's reference list, JSTOR is the second container for articles one reads via JSTOR. Leaving it out indicates one reads the article directly from the journal, changing what a reader needs to know to retrieve it.

6. Inconsistent in-text and Works Cited entries. Every in-text citation must match a Works Cited entry by the first element (usually the author's last name). If your in-text cites "Smith" and your Works Cited has "Smith, J. R.," the match works. If the in-text cites "Smith and Jones" and the Works Cited has only "Smith, J. R.," that is a problem reviewers spot in seconds.

7. Et al. used too early or too late. "et al." begins with the first citation for three or more authors under MLA 9. MLA 7 has no limit, and MLA 6 limited it to four. One can find old templates. Check the one one is using.

The only realistic way to check all seven of those patterns at once when one's essay has 60 entries and a deadline is to use a proofreader that keeps track of academic citations.

Citation tools that actually understand MLA 9

The right tool depends on what you are doing.

To create a single MLA citation and get it into the body text cleanly, a mla citation generator works just fine. Scribbr, MyBib, and BibGuru will create MLA 9 citations based on a DOI, ISBN, or URL. Our AI proofreader will also create MLA 9 citations in addition to APA 7, Chicago 17, IEEE, Harvard, Vancouver, Turabian, and AMA right inside the same editor where one is writing the rest of one's essay, avoiding having to shift contexts entirely.

To audit an existing list of Works Cited for errors, one wants a citation checker apa mla chicago workflow. It will read one's list of Works Cited and make sure they're consistent with one another (like if they use different formatting). Some good options include Akowe and ReferenceChecker.org. Ours works within the proofreader itself so one can correct the citations as part of correcting the text.

One may want to go even deeper than that, though, if one is doing an entire proofread on a big paper or book. Ideally, it would find in-text citations that don't match anything in one's list of Works Cited, unmatched citations, unlisted containers, commas after author names, and the et al. rule mismatches listed above. Our AI proofreader will do all that for one on every manuscript. Depth vs. Speed When one needs a single citation quickly, a generator is faster. But if one has a long essay with 60 Works Cited entries to check, using a proofreader that also checks one's citations will save one hours of time.

Our broader citation formatting overview compares MLA, APA, Chicago, and IEEE side by side if you are switching styles between an essay and a thesis chapter. If you are also rewriting passages around your citations, our note on paraphrasers that preserve citations covers why generic rewriters tend to break parenthetical citations and what to look for instead.

Frequently asked questions

Q: How do I cite ChatGPT in MLA 9?

Cite the chatbot only when its output is part of your essay, treat the prompt as the source title in quotation marks, italicize the tool name as the container, and list the publisher and date. The template is: "Prompt text" prompt. ChatGPT, version, OpenAI, Day Month Year, URL. The in-text citation uses the shortened prompt in quotation marks: ("Prompt"). Keep the full prompt and response in an appendix when the output is doing analytical work in your argument.

Q: What is the difference between MLA 8 and MLA 9?

MLA 9 keeps the container model from MLA 8 and expands the guidance around it. The headline additions are a chapter on inclusive language, fuller guidance on annotated bibliographies (3 to 7 sentences each is the recommendation), more digital and AI examples, and a new chapter on plagiarism and academic integrity. The in-text rules are unchanged: author-page, no comma, et al. for three or more authors.

Q: Why no comma between author and page in MLA citations?

That is the MLA convention and always has been. APA, Chicago author-date, and Harvard all use commas; MLA uses spaces. The rule predates the digital era and predates the container model. If you cannot remember it, write your essay in MLA throughout and your eye will adapt; switching styles every chapter is what breaks the habit.

Q: Do I include URLs in my Works Cited?

Include a URL or DOI if it is accessible. If not, state where the material was located. MLA 9 recommends including a URL or DOI for any source you accessed online when the link is stable. For a journal article accessed through a database, include the DOI if available and add the database name as the second container. For a website, include the URL without "https://" by default, though leaving the protocol in is also accepted. For sources behind paywalls that change links often, judgment is allowed: list the source's home page or omit the URL entirely.

Q: Do I need to disclose AI use if I cite the LLM in my Works Cited?

Yes, citation and disclosure are separate. The citation tells the reader where a specific quote or output came from. The disclosure statement tells the reader how AI tools shaped the essay overall. Most journals and many graduate programs now require both. See our guide to writing an AI use disclosure statement for the templates publishers and institutions currently accept.
