Chicago vs Harvard
Updated September 2026
Chicago (17th edition) is the standard in history, art history, and publishing. Harvard (author–date) is the standard in UK, Australian, and international universities across disciplines. They differ in how they cite in the text, how they format references, and what they emphasize — Chicago prioritizes uninterrupted prose — discussion happens in the notes; Harvard prioritizes author–date clarity with institution-specific variants.
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: Chicago — a footnote: ¹ Björn Rasch and Jan Born, … 685.; Harvard — (Rasch and Born, 2013).
- Reference list title: Chicago — Bibliography; Harvard — Reference List.
- Ordering: Chicago alphabetizes by author; Harvard alphabetizes by author.
- Chicago traits: First author inverted, additional authors in natural order; Titles use Title Case; articles in quotes, containers in italics.
- Harvard traits: All authors inverted with initials, joined by 'and' (no ampersand); Article titles take 'single quotation marks'; containers are italicized.

How citing in the text differs
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.
Harvard: Harvard cites in the text with author and year, comma included: (Alvarez, 2024), adding a page for quotes: (Alvarez, 2024, p. 12). Three or more authors use et al.: (Harris et al., 2020). Named in your sentence, only the year is parenthesized: Alvarez (2024) argues…
Which should you use?
Whatever your assignment, department, or journal requires — that overrules everything. When the choice is genuinely yours: pick Chicago if your work sits in history, art history, and publishing, and Harvard for UK, Australian, and international universities across disciplines. Structurally, choose Chicago when uninterrupted prose — discussion happens in the notes matters more to your readers, and Harvard when author–date clarity with institution-specific variants 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.
