Books are among the most commonly cited source types in academic writing — and among the most frequently miscited. The differences between APA, MLA, and Chicago book citation formats are significant enough that a citation correct in one style is wrong in another: publisher location is required in Chicago but omitted in APA 7th edition; author names use full first names in MLA but initials only in APA; italicisation rules differ across all three styles.
This guide gives you the exact format for every common book citation scenario in APA 7th edition, MLA 9th edition, and Chicago 17th edition. Each section includes copy-ready examples you can adapt directly, along with explanations of the rules behind each element so you can handle unusual cases with confidence.
Once you have your citations formatted, run them through an automated reference checker before submission to catch any formatting errors your eye might miss.
Quick Reference: Basic Book Format by Style

Citing a Book in Chicago 17th Edition
Chicago offers two systems — Notes-Bibliography (humanities) and Author-Date (sciences). Both are covered below.
Chicago 17th Edition — Key book citation rules
- • Publisher location is required — this distinguishes Chicago from APA and MLA
- • Notes-Bibliography: footnotes use normal name order (First Last); bibliography inverts first author (Last, First)
- • Author-Date: reference list inverts first author; in-text uses (Last Year, page)
- • Book titles in italics, headline style (all major words capitalised)
- • Publication info in parentheses in footnotes, but not in bibliography entries
- • Well-known city names (New York, London, Chicago) do not need a country or state
Single Author — Notes-Bibliography
Used in history, literature, arts, and most humanities disciplines
Footnote / Endnote (first reference)
Footnote (subsequent references — shortened form)
Bibliography entry
Two or Three Authors — Notes-Bibliography
Footnote format
Bibliography entry
Four or more authors: In the footnote, list all authors or use the first author followed by "et al." In the bibliography, list all authors up to ten; for eleven or more, list the first seven followed by "et al."
Edited Book — Notes-Bibliography
Footnote
Bibliography entry
Chapter in an Edited Book — Notes-Bibliography
Footnote
Bibliography entry
Single Author — Author-Date System
Used in social sciences, natural sciences, and some business disciplines
Reference list entry
Example
In-text citation
Ebook — Notes-Bibliography
For ebooks with stable DOIs, prefer the DOI over the URL. For ebooks accessed through a database, include the database name.
Bibliography entry (with DOI)
Side-by-Side Comparison: The Same Book in All Three Styles
The following examples all cite the same book — Malcom Gladwell's Outliers (2008, Little, Brown and Company, New York) — formatted correctly in each style. This makes the differences between styles immediately visible.
APA 7th Edition
Gladwell, M. (2008). Outliers: The story of success. Little, Brown and Company.
In-text: (Gladwell, 2008) or (Gladwell, 2008, p. 42)
MLA 9th Edition
Gladwell, Malcolm. Outliers: The Story of Success. Little, Brown and Company, 2008.
In-text: (Gladwell 42)
Chicago 17th — Bibliography
Gladwell, Malcolm. Outliers: The Story of Success. New York: Little, Brown and Company, 2008.
Footnote: Malcolm Gladwell, Outliers: The Story of Success (New York: Little, Brown and Company, 2008), 42.
| Element | APA 7th | MLA 9th | Chicago 17th |
|---|---|---|---|
| Author names | Surname, Initials | Surname, Full first name | Surname, Full first name (bibliography) |
| Year position | After author, in parentheses | Near end of entry | Near end (NB); after author (AD) |
| Title case | Sentence case | Title case | Title case |
| Publisher location | Not included | Not included | Required |
| In-text format | (Author, Year, p. X) | (Author Page) | Footnote¹ or (Author Year, page) |
Most Common Book Citation Mistakes
Including publisher location in APA 7th edition
APA 7th edition no longer requires the city of publication. If you are still writing "New York, NY: Publisher" in APA format, you are using APA 6th edition rules. Remove the location entirely.
Using APA-style initials in MLA
MLA requires full first names, not initials. "Gladwell, M." is incorrect in MLA — it should be "Gladwell, Malcolm." This is the reverse of APA, which uses initials only.
Wrong title capitalisation
APA uses sentence case for book titles (only the first word and proper nouns capitalised). MLA and Chicago use title case (all major words capitalised). Copying a title from a publisher's website — which uses house style — is a common source of this error.
Omitting publisher location in Chicago
Chicago 17th edition still requires the city of publication for books, unlike APA and MLA. A Chicago bibliography entry without a city is incomplete.
Citing the chapter author when you mean the book editor
When citing a specific chapter in an edited book, the in-text citation should name the chapter author, not the book editor. The editor appears only in the reference list entry as part of the book information.
Not specifying the edition
If a book has multiple editions and you are using a specific edition, you must include the edition number. Omitting it could misdirect readers to a different version with different page numbers and content.
Frequently Asked Questions
Do I need to include page numbers when citing a book?
For direct quotations, page numbers are always required in all three styles. For paraphrasing or general reference to a book's argument, APA and Chicago make page numbers optional (though they are recommended for precision), while MLA requires a page number whenever one is available. If you're citing a general idea spread across an entire book rather than a specific passage, omit the page number and note the book as a whole.
How do I cite a book I read online through a library database?
In APA, treat it like an ebook and add the DOI or database URL at the end. In MLA, add the database name as a second container after the print publication information, followed by the URL. In Chicago, include the database name and URL after the standard print citation information. If the book has a DOI, use that instead of the database URL, as DOIs are more stable.
What if the book has no author?
If a book has no identified author, all three styles begin the citation with the title. In APA, the title moves to the author position. In MLA and Chicago, the same applies. For in-text citations in APA, use a shortened version of the title in italics; in MLA, use the title (shortened if long) in italics; in Chicago, use the title in shortened form in the footnote.
How do I cite a translated book?
All three styles include the translator's name, but in different positions. In APA: Author. (Year). Title (A. Translator, Trans.). Publisher. In MLA: Author Last, First. Title. Translated by First Last, Publisher, Year. In Chicago bibliography: Author Last, First. Title. Translated by First Last. City: Publisher, Year.
How do I cite a republished or classic book?
For republished books, include both the original publication date and the republication date. In APA: Author. (Republication Year). Title (Original work published Year). In MLA, include the original date before the publisher and the reprint date after. Chicago allows a note format: "Originally published [Year]." Check your specific edition's guidelines for the precise placement.
Conclusion
The core structure of a book citation is the same across all three styles — author, title, publisher, year — but the differences in how each element is formatted are significant enough to matter. Publisher location, author name format, title capitalisation, and the position of the year in the entry all differ between APA, MLA, and Chicago.
The most reliable approach is to keep the official style guide for your required format accessible while you write, verify each citation immediately when you add it rather than leaving it until submission, and run a final automated check across your complete reference list before you submit.
One error that consistently catches researchers out: citation generators and reference management software frequently produce book citations that are subtly wrong — outdated edition rules, incorrect capitalisation, missing publisher location in Chicago. Always verify generated citations rather than submitting them unchecked.
Verify Your Book Citations Before Submission
Upload your document and catch formatting errors across APA, MLA, Chicago, IEEE, and AMA automatically.
