MLA vs Chicago
Updated September 2026
MLA (9th edition) is the standard in English, literature, languages, and the humanities. Chicago (17th edition) is the standard in history, art history, and publishing. They differ in how they cite in the text, how they format references, and what they emphasize — MLA prioritizes where a passage lives in the text — page-level precision; Chicago prioritizes uninterrupted prose — discussion happens in the notes.
Your field or instructor decides which you need. Here are the differences that matter, side by side.
The differences at a glance
- In-text citation: MLA — (Rasch and Born 685); Chicago — a footnote: ¹ Björn Rasch and Jan Born, … 685..
- Reference list title: MLA — Works Cited; Chicago — Bibliography.
- Ordering: MLA alphabetizes by author; Chicago alphabetizes by author.
- MLA traits: Only the first author's name is inverted; co-authors appear in natural order with full first names; Titles use Title Case — capitalize all principal words.
- Chicago traits: First author inverted, additional authors in natural order; Titles use Title Case; articles in quotes, containers in italics.

How citing in the text differs
MLA: MLA cites in the text with author and page: (Alvarez 12) — no comma, no year. Sources without page numbers (most web sources) cite the author alone: (Alvarez). Three or more authors use et al.: (Harris et al. 360).
Chicago: Chicago's notes-bibliography system cites with footnotes: a superscript number in the text pointing to a note with the source details and page. The bibliography entry shown here contains everything the footnote needs — un-invert the author's name and swap most periods for commas to form the note.
Which should you use?
Whatever your assignment, department, or journal requires — that overrules everything. When the choice is genuinely yours: pick MLA if your work sits in English, literature, languages, and the humanities, and Chicago for history, art history, and publishing. Structurally, choose MLA when where a passage lives in the text — page-level precision matters more to your readers, and Chicago when uninterrupted prose — discussion happens in the notes does.
Then be perfectly consistent — a clean paper in either style beats a hybrid of both, and mixed styles are the first thing graders notice. Since the generator renders both styles from one paste, switching late costs nothing.
