How to Cite a Book in APA, MLA, Chicago, and Four More Styles

By MLA Generator Editorial Team · Published April 15, 2026

Books look like the simplest source type — a name, a title, a publisher, a year — and the basic single-author book really is simple. The complications start as soon as a real assignment introduces the second author, the editor, the second edition, the translator, the chapter in the edited volume, the foreword by someone else, the digital-only release. This guide covers the basic format in each of the seven major styles, the same book and the same chapter formatted side by side across all of them, and the variations that come up in actual research.

The shortest answer: get the author’s full name, the book title, the publisher, and the year. Cite that in your chosen style’s format. For chapters in edited books, also collect the chapter title, the editor’s name, and the chapter’s page range — those are non-negotiable in every style.

What counts as a “book”

For citation purposes, a book is a self-contained work issued by a publisher with its own ISBN or equivalent identifier, regardless of whether you read it in print, on a Kindle, on a library platform like ProQuest Ebook Central, or in PDF form. The format barely matters; what matters is the work.

If the work you read is genuinely a book — a monograph, a collection of essays, a textbook, a memoir, a translated novel, a multi-volume reference set — this page applies. If what you read is something that looks like a book but is actually a different source type, the dedicated guide handles it:

• A peer-reviewed article that happens to be released as a long PDF is still a journal article.
• A government report, white paper, or working paper — even when it has a title page and an ISBN — usually cites as a report, not a book.
• A doctoral or master’s thesis is its own category in every style, distinct from “book” even though most universities now release theses as PDFs.

The structural decision after that is whether you read the whole book by one author or a single chapter from a book with chapters by different authors. The two cases produce different reference entries; everything else is consistent.

Information to collect before you cite

For a single-author or co-authored book, collect:

• Author or authors — full name in the order shown on the title page. Take the spelling from the title page, not the cover.
• Book title and subtitle — from the title page. Subtitles separated by a colon are part of the title in every style.
• Edition — when the book is not the first. The number is on the copyright page near the ISBN.
• Publisher — the imprint shown on the title page. If the title page shows several cities, use the first.
• Year of publication — the most recent copyright year on the copyright page. If the book is a reprint of an earlier work, both years may matter (see “Republished or classic work” below).

For a chapter in an edited book, also collect:

• Chapter author or authors
• Chapter title
• Editor or editors of the volume — labeled “Edited by” or “Ed.” on the title page
• Page range of the chapter — first to last page

A book’s generator entry on this site captures most of these fields from an ISBN or title search. As always, eyeball the generated citation against the actual title page — the first three fields are the ones that drift most often when metadata is incomplete.

A single-author book, formatted in all seven styles

The source: Margaret S. Chen. The Architecture of Working Memory. Cambridge University Press, Cambridge, UK, 2021.

The visible differences are predictable. APA, MLA, and AMA omit the publisher city — APA and AMA dropped it in their most recent editions, and MLA 9 leaves it out of its standard core-elements format. Chicago 18 makes it optional but still common in humanities work, and the example here keeps it. Harvard, Vancouver, and IEEE still routinely include the city. APA, Harvard, and Vancouver use lowercase (sentence case) for the title; MLA, Chicago, IEEE, and AMA use title case. APA, MLA, Chicago, Harvard, and IEEE italicize the title; Vancouver and AMA do not — though AMA italicizes book titles when standing alone in a reference, which is the case here. Year placement varies: APA and Harvard parenthesize it after the author; MLA, Chicago, IEEE, and AMA push it later; Vancouver puts it after the publisher with a semicolon.

The in-text citation for the same source:

• APA, Harvard: (Chen, 2021) — add a page number when quoting: (Chen, 2021, p. 47)
• Chicago author–date: (Chen 2021) — Chicago drops the comma between author and year; add a page number with a comma: (Chen 2021, 47)
• MLA: (Chen 47)
• Vancouver, AMA: (1) or superscript ¹ in citation order
• IEEE: [1]

A chapter in an edited book, formatted in all seven styles

When you read a chapter in a collection edited by someone else, the chapter is the unit you cite, not the whole book.

The source: David K. Lin and Hannah J. Patel. “Cross-Modal Attention in Early Development.” In Handbook of Developmental Cognition, edited by Rachel T. Morrison, pages 142–168. Routledge, London, 2022.

The structural pattern is the same in every style: chapter author, chapter title, “In:” or “In”, editor with appropriate label, book title, publisher, year, page range. What changes is the punctuation around each piece. Notice that quoted titles versus italicized titles split the styles in the same way they did for the single-author book — the chapter title takes the article-equivalent treatment, the book title takes the book-equivalent treatment.

When your book has variations

Multiple authors. Up to about three authors, list every name in the order shown on the title page. With more authors, the threshold for collapsing to “et al.” varies: APA 7 uses et al. starting at three authors in-text but lists up to 20 in the reference list before an ellipsis. MLA uses et al. starting at three in both places. Chicago 18 lowered its in-text threshold to three or more (it was four in CMS 17) and lists up to six authors in the reference list before collapsing to “First three et al.” Harvard (Cite Them Right) keeps its threshold at four or more. Vancouver, IEEE, and AMA each set their own thresholds — see the dedicated style guides.

A specific edition. Every style includes the edition number when it is anything other than the first.

APA: Chen, M. S. (2024). The architecture of working memory (2nd ed.). Cambridge University Press.

MLA: Chen, Margaret S. The Architecture of Working Memory. 2nd ed., Cambridge University Press, 2024.

Chicago: Chen, Margaret S. 2024. The Architecture of Working Memory. 2nd ed. Cambridge: Cambridge University Press.

A translated work. Cite the original author and add the translator’s name with the style’s standard label. The original publication year is included when the gap between original and translation matters to your argument; otherwise the translation year alone is sufficient.

APA: Beauvoir, S. de. (2010). The second sex (C. Borde & S. Malovany-Chevallier, Trans.). Vintage. (Original work published 1949)

MLA: Beauvoir, Simone de. The Second Sex. Translated by Constance Borde and Sheila Malovany-Chevallier, Vintage, 2010.

An e-book or audiobook. In APA 7, Chicago 18, and MLA 9, the format is not part of the citation unless it changes the content. When the format does matter — different pagination, no pagination, audiobook narration that differs from print — add a format note: “[E-book]” or “[Audiobook]” for APA, “Kindle ed.” for MLA, “Audiobook” for Chicago. For an e-book without page numbers, use a chapter, section, or location locator in the in-text citation instead of a page number.

A book in a multi-volume set. Cite the specific volume you used, with its title if the volume has one. APA: “Chen, M. S. (2021). The architecture of working memory: Vol. 2. Application. Cambridge University Press.” If your citation pulls from the whole multi-volume work, treat the set as one work and include the volume count: “(Vols. 1–3)” in APA, “3 vols.” in MLA.

Edge cases

No named author. Move the title to the front, exactly where the author would have gone. Most “books with no author” are reference works or institutional publications — in those cases, the organization is usually the author and you should check the title page and copyright page before defaulting to title-first.

Organization as author. Spell out the organization name on first in-text mention; some styles permit a defined abbreviation thereafter. The reference list entry always uses the full name.

APA: National Academy of Medicine. (2022). Health system resilience after a pandemic. National Academies Press.

Foreword, introduction, or preface by a different person. Cite the foreword author and indicate the role.

MLA: Sontag, Susan. Foreword. The Origin of Others, by Toni Morrison, Harvard University Press, 2017, pp. ix–xviii.

Republished or classic work. When citing a modern reissue of an older work — Aristotle’s Politics in a 2017 Penguin paperback, for example — include both the original year and the reissue year. APA: (Aristotle, ca. 350 B.C.E./2017). MLA and Chicago insert the original date into the entry with a “Originally published” note or include both years.

Books from a series with their own numbering. Series matter when the volume number identifies the specific work. APA: “Chen, M. S. (2021). The architecture of working memory (Cambridge Studies in Cognition, Vol. 14). Cambridge University Press.” MLA and Chicago use a similar parenthetical.

A final principle: the title page is the source of truth, not the cover, not the spine, not the Amazon listing, not the publisher’s catalog page. If the title page disagrees with the cover, cite what the title page says — that’s what every style assumes you did.
