MLA vs Chicago: Author-Page or Notes for the Humanities?

MLA vs Chicago: Quick Answer

Use MLA when the course is in literature, languages, composition, or cultural studies and the reader needs a page, line, or time stamp more than a year. Use Chicago notes-bibliography when the course is in history, art history, religion, or music and the argument needs footnotes, archival sources, or commentary beside the citation. If the syllabus, journal, or press names a style, that instruction wins over any field custom. For a compact pair table, see the MLA vs Chicago comparison.

Those are two official books, not one source restyled three ways. Older MLA vs Chicago charts still paste Zadie Smith's Swing Time as the Chicago book. That was the CMOS 17 Quick Guide specimen. The live CMOS 18 Notes and Bibliography samples use Charles Yu's Interior Chinatown. Same-source restylings later on this page are labeled applied.

Current Editions: MLA 9th vs Chicago 18th

The comparison only holds if you are using the editions instructors now expect. The MLA Handbook, 9th edition, was published by the Modern Language Association in 2021 and is still the current MLA book in 2026. In-text rules live in sections 6.3–6.30; the Works Cited template is chapter 5. The MLA Style Center asked instructors in May 2026 how the next handbook should treat database names. That survey is research for a future edition, not a live MLA 10. Cite from the ninth edition until the Association publishes a successor.

The Chicago Manual of Style, 18th edition, was published by the University of Chicago Press in September 2024 and replaced the 17th edition (2017). Citation overview is chapter 13; source-type examples are chapter 14. Kate L. Turabian's A Manual for Writers, 9th edition, is still the student companion and still follows CMOS 17. Turabian 10 has been announced; the Turabian home page still describes the ninth edition.

That edition change is the usual trap. Many older MLA vs Chicago charts still say Chicago requires a city of publication. CMOS 18 no longer requires a place of publication for books (see CMOS 14.30). MLA 9 already treated city of publication as rarely needed (5.67). For a modern book, both styles now omit the city.

How the Official Handbooks Describe Themselves

The deepest MLA vs Chicago difference is not a comma. It is what each style wants the reader to notice first. MLA is built so a literary argument can point to a passage. Chicago's notes system is built so a historian can document an unusual source and, if needed, talk about it in the note.

Those sentences come from the MLA Handbook, 9th edition product page, the MLA Style Center in-text overview, and the Chicago-Style Citation Quick Guide. They are the shortest accurate definition of the MLA vs Chicago choice: a concise pointer to a passage versus a flexible note, usually in the humanities.

What Each In-Text Citation Is Designed to Show

MLA's parenthetical form is author and page, with no comma and no p. A narrative citation puts the name in the sentence and leaves only the locator in parentheses. If you mention the author and you are not pointing to a specific part of the work, MLA 6.2–6.3 lets the sentence itself do the work. Section 6.26 covers sources that have no page or part numbers. The year stays in the Works Cited entry. That is why copying a Chicago author-date parenthesis into an MLA paper — or the reverse — is easy to spot.

The Style Center also warns that restating the author in both the prose and the parentheses is incorrect: do not write (Baron 194) after a sentence that already says Naomi Baron. Chicago notes-bibliography keeps that sentence clean. The superscript number goes after the punctuation. The first note is a full citation. Later notes use a shortened form. CMOS 18 prefers those shortened notes over ibid. (13.37). Chicago author-date puts the year in the parenthesis and still does not use p.

Chicago's Two Systems (This Is the Usual Confusion)

"Chicago style" is not one citation format. The 18th edition still contains two complete systems. You pick one for the whole paper. Mixing a footnote with a parenthetical author-date citation is a style error, not a personal preference. The Quick Guide says most authors follow their field or publisher, and students should check with the instructor.

Notes and bibliography

Numbered footnotes or endnotes carry the citation. A bibliography at the end usually lists the sources. CMOS calls this its oldest and most flexible system, and it is the default in history, art history, religion, music, and many book manuscripts. Literature seminars sometimes use it too — that is why "humanities" is not a synonym for MLA. For the field walkthrough, see how to cite sources in history.

Author-date

Parenthetical citations name the author and year in the sentence, and a reference list at the end holds the full entries. CMOS recommends this system in the sciences and social sciences. It is the Chicago form that looks a little like MLA at a glance and is not MLA: the year is required, there is no comma between author and year, and a page number does not use p. If your history syllabus says Chicago, do not assume author-date. Ask which system.

In-Text Citations Compared

The two-author row is a live failure mode. MLA joins names with and. Chicago notes and author-date also use and, never an ampersand. APA is the style that wants & in parentheses. If you are deciding among all three, use APA vs MLA or APA vs Chicago instead of this page.

Works Cited vs Bibliography

A Chicago bibliography can be broader than an MLA Works Cited list. Humanities projects often include sources that shaped the argument even if a specific page was never quoted. MLA is stricter: if it is in Works Cited, you cited it. That is why "I used Chicago but labeled the list Works Cited" is a common mix-up on student papers. Walk through the end-list job in how to write a bibliography.

Official Books Side by Side

The MLA Style Center uses Hilary Mantel's Wolf Hall (Picador, 2010) as its one-author book. The CMOS 18 Quick Guide uses Charles Yu's Interior Chinatown (Pantheon Books, 2020). The Chicago forms applied to Mantel below follow CMOS 18: no city of publication. They are not printed on the Style Center page. For more book patterns, see how to cite a book in MLA and how to cite a book in Chicago.

For a simple modern monograph, the MLA Works Cited line and the Chicago bibliography line can look almost identical. The live difference is the citation in the sentence: MLA points with (Mantel) or (Yu 45), Chicago notes with a superscript, and Chicago author-date with (Yu 2020, 45). Two authors stay visible in both styles. The official CMOS pair is Amy J. Binder and Jeffrey L. Kidder:

The publisher line is the giveaway. MLA 5.64–5.65 shortens University of Chicago Press to U of Chicago P. Chicago spells the publisher the way the title page does. Do not carry UP into a Chicago note, and do not spell out University Press in an MLA Works Cited entry.

Official Journal Articles Side by Side

Journal articles are where the two styles stop looking alike. MLA names the container, writes vol. and no., uses pp., keeps a month or lowercase season when the issue prints one, and can treat a database as a second container. Chicago writes volume and issue as 50, no. 2 (2023): 225–51 and prefers a DOI written as a URL (CMOS 13.7). CMOS 18 also says a month or season can usually be omitted from a journal citation (13.26). Walk through more patterns in citing a journal article in MLA and citing a journal article in Chicago.

The applied Chicago line drops spring, writes 64, no. 1 (2010), turns the hyphenated MLA page span into an en dash, and prefers a full https:// JSTOR URL over the truncated Style Center form. That is CMOS 13.26 and 13.7 talking, not a second official Goldman specimen.

The year mismatch is a real rule, not a typo. The official CMOS specimen writes 2023. The Critical Inquiry issue page labels volume 50, issue 2 as Winter 2024, and Crossref lists the article as published 22 November 2023. CMOS 13.26 lets the note keep the year only. MLA 5.73 and 5.79 take the issue date the journal printed and lowercase the season. Quote the Quick Guide when you are matching Chicago. In an MLA paper, write winter 2024 from the issue you opened.

MLA's Container Template vs Chicago's Source-Type Chapters

MLA 8 introduced, and MLA 9 kept, a single template of nine core elements: Author; Title of source; Title of container; Other contributors; Version; Number; Publisher; Publication date; Location. You include only the elements the source actually has. A journal article in JSTOR has two containers: the journal, then the database.

Chicago does not use that vocabulary. CMOS 14 is a catalog of source types: book, chapter, journal, newspaper, interview, dissertation, web page, social post, video. The flexibility lives in the note, which can describe a manuscript, a letter, or a source that does not fit a template. That is why Chicago remains the usual choice for archival work even when the writer's home field also uses MLA. See citing archival sources in Chicago and citing manuscripts in Chicago. For the literature-side container walkthrough, see citing sources in literary studies.

Publisher Names, Location, and Other CMOS 18 Updates

MLA shortens University Press to UP and drops business words such as Company or Inc. (5.64–5.65). Chicago spells the publisher the way the title page does, without that UP shortcut. CMOS 18 then dropped the city that older Chicago handouts still teach. The What's New in the 18th Edition list is the shortest official changelog:

• Place of publication: Omit it in CMOS 18. MLA 9 already omitted it for most modern books. For books before 1900, Chicago often prefers the city instead of a publisher name (14.31).
• DOI form: Chicago wants https://doi.org/.... The older doi: prefix is deprecated (13.7). MLA will accept a DOI, a permalink, or a truncated URL; the official Goldman example uses a JSTOR URL without https://.
• Chapter page ranges: A Chicago bibliography entry for a chapter in an edited book no longer needs the chapter's page range (14.8). Journal articles still need the article page range.
• Author lists: CMOS 18 lists up to six authors in a bibliography; more than six becomes the first three plus et al. In a note, three or more authors become first author plus et al. (13.23). MLA 9 uses et al. after two authors in both the Works Cited entry and the in-text citation (5.8, 6.5).
• Repeated names: CMOS 18 prefers repeating an author's name instead of a 3-em dash (13.72). MLA uses three hyphens for a repeated author in Works Cited (5.126).
• AI tools: CMOS 18 includes chatbot guidance (14.112). MLA has Style Center posts on citing generative AI. See how to cite ChatGPT and AI tools.

Repeated Sources and the End of ibid.

MLA repeats a concise parenthetical citation as needed and tells you not to restate the author in both the prose and the parentheses. Chicago used to let consecutive notes say ibid. CMOS 18 is clearer:

If you learned Chicago from a 17th-edition handout that still recommends ibid., update the habit. The official short form for Interior Chinatown is Yu, *Interior Chinatown*, 48 — not ibid., 48. Older pages on this site that still show Smith, *Swing Time*, 320 are quoting the previous Quick Guide book, not a second current specimen.

When to Use MLA vs Chicago

Use MLA when

• The syllabus, writing program, or journal names MLA.
• The paper is a close reading of a novel, poem, play, film, or performance and the reader needs a page, act/scene/line, or time stamp.
• The course sits in literature, languages, composition, film studies, or cultural studies.
• You are citing a source inside a source — an essay in an anthology, an article in a database — and the container template is the shortest accurate description. See citing an anthology in MLA, citing a poem in MLA, and citing a play in MLA.

Use Chicago when

• The syllabus, thesis office, or press names Chicago or Turabian.
• The paper is historical and the notes need room for archival IDs, commentary, or sources that do not fit a nine-element template.
• The course sits in history, art history, religion, musicology, or another field that still publishes in notes.
• You are writing a book manuscript for a press that edits to CMOS. For the student handbook that still follows CMOS 17, see Turabian vs Chicago.

Field custom is a fallback, not a license. An English seminar on revolutionary France still uses MLA if the syllabus says MLA. A history seminar on the same novels still uses Chicago notes if the department says Chicago. If you may truly choose, match the evidence: passage-level literary analysis belongs in MLA; archival and note-heavy historical work belongs in Chicago. For the wider map, see which citation style to use and citation styles by discipline.

Paper Format Students Mix Up

Citation style and first-page format travel together. MLA is more prescriptive for student papers. Chicago leaves more layout to the instructor, department, or Turabian. For shared academic-paper basics, see how to format academic papers.

Common Mistakes

• Putting a year in an MLA parenthesis because a Chicago or APA example had one. MLA's default is (Baron 194), not (Baron 2013, 194).
• Adding `p.` in MLA or Chicago. That abbreviation is an APA habit.
• Using MLA parenthetical citations with Chicago notes-bibliography. Pick one system.
• Keeping a city of publication in Chicago. CMOS 18 dropped it for modern books.
• Writing `doi:10...` in Chicago. CMOS 13.7 wants the https://doi.org/ form.
• Labeling a Chicago list Works Cited, or an MLA list Bibliography. The heading is part of the style.
• Leaning on ibid. Use the CMOS 18 shortened note.
• Abbreviating University Press as `UP` in Chicago, or spelling it out in MLA. Each style has its own publisher rule.
• Treating Swing Time as the current CMOS book specimen. The live Quick Guide book is Yu, Interior Chinatown.
