MLA vs. Chicago: a side-by-side comparison

MLA and Chicago both rule the humanities. They don't look alike. MLA does parenthetical author-page markers and ends with a Works Cited list. Chicago notes-bibliography does footnotes and a separate bibliography. This guide walks through the differences rule by rule. Our citation generator spits out either format from any source.

When the humanities use which

MLA and Chicago run the humanities between them. The split is disciplinary. MLA owns English, modern languages, and literary studies. Chicago owns history, art history, philosophy, and religion.

Chicago comes in two flavors. Notes-bibliography is the canonical humanities form. Author-date shows up in the social sciences. When a humanities scholar says "Chicago," they mean notes-bibliography. Nearly always.

How citations appear in the text

MLA — parenthetical

Bishop describes the moose in the bus aisle as "homely as a house" (12).

Chicago NB — footnote

Bishop describes the moose in the bus aisle as "homely as a house."1

MLA marks citations with parenthetical author-page tags. Chicago NB uses superscript note numbers that point to footnotes (or endnotes) at the bottom of the page. The two look nothing alike on the page. You can spot the difference at a glance.

First citation example

MLA — Works Cited entry

Bishop, Elizabeth. "The Moose." Geography III, Farrar, Straus and Giroux, 1976, pp. 12–18.

Chicago NB — full footnote

1. Elizabeth Bishop, "The Moose," in Geography III (New York: Farrar, Straus and Giroux, 1976), 12.

Same bibliographic content. Different punctuation. MLA leans on commas. Chicago NB notes shift the commas around and wrap parentheses around the publisher.

Subsequent citations

MLA just repeats the parenthetical. (Bishop 14) for a quote from page 14. Chicago NB switches to a shortened note the second time around: 2. Bishop, "The Moose," 14.

MLA never uses footnotes for citations. If you see footnotes in an MLA paper, they're usually content notes (extra commentary), not source citations. Chicago, by contrast, builds its entire citation system on footnotes.

Works Cited vs. Bibliography

MLA papers close with a Works Cited list. Every source you cited. Chicago NB papers close with a Bibliography. Every source you consulted, whether you cited it or not.

MLA — Works Cited entry

Said, Edward. Orientalism. Pantheon Books, 1978.

Chicago NB — Bibliography entry

Said, Edward. Orientalism. New York: Pantheon Books, 1978.

The Chicago bibliography entry looks a lot like a footnote, just rearranged. Periods where the note had commas. Publication city sits before the publisher.

Page numbers

MLA wants page numbers on quotes and paraphrases both — "works cited at the page" is a core MLA principle. Chicago NB also expects a page in the footnote whenever you make a specific claim. The split is where the number goes. MLA: in parentheses, inline. Chicago: tucked at the end of the footnote.

MLA — page in parens

Said argues that "the Orient was almost a European invention" (1).

Chicago NB — page at end of footnote

1. Said writes that "the Orient was almost a European invention."1 ↳ 1. Edward Said, Orientalism (New York: Pantheon, 1978), 1.

When to use MLA over Chicago (and vice versa)

Reach for MLA when you're writing about one specific text. A poem. A novel. A film. The author-page form keeps you anchored to the page you're analyzing.

Reach for Chicago NB when your project pulls from a mess of source types: primary documents, archival material, secondary literature, interviews. Footnotes give you room to add discursive commentary that a parenthetical never could.

If your discipline isn't dictating one for you, it usually comes down to taste. Do you want page-bottom notes (Chicago) or a cleaner reading surface (MLA)? Pick.
