How to Cite a Book: Authors, Editions, Chapters and Publishers

The information every book citation needs

A book is one of the most straightforward sources to cite, because most of the information you need is printed on the title page and the page behind it, often called the copyright page. Gather the author or authors, the full title and any subtitle, the edition if it is not the first, the publisher, the year of publication, and for some styles the place of publication. If you used an electronic version, also note the platform or link, and a DOI if the book has one.

Always take the information from the book itself rather than from a retailer page or catalogue. Retailers sometimes list the date of a reprint or a different edition. Library catalogues are usually more reliable but may still contain errors. If your copy is a reprint, check whether the style asks for the original date, the reprint date, or both. This is one of the details that varies, so confirm it in your manual.

This guide describes general patterns only. Your instructor or the current manual for your style decides the exact punctuation and order.

A generic pattern for each major style

In APA 7, a generic book entry is Author, A. A. (Year). Title of work: Subtitle (Edition). Publisher. The title is italicized with sentence-style capitalization, and the publisher is given without the place of publication. In MLA 9, the generic form is Author Surname, First Name. Title of Work: Subtitle. Publisher, Year. The title is italicized with headline-style capitalization.

In Chicago notes-bibliography, a bibliography entry looks like Surname, First Name. Title of Work: Subtitle. Place of Publication: Publisher, Year. A note for the same book places the author name in normal order and puts the publication details in parentheses followed by the page number. In Harvard, many versions follow Surname, A. A. (Year) Title of work. Edition. Place: Publisher, though the details vary between institutions.

These patterns are placeholders, not examples of real sources. When you fill them in, use the exact title and names printed in your book. If you cannot tell which element is the subtitle, look at the title page. Most styles separate title and subtitle with a colon, even when the cover uses a different design.

Editors, translators and editions

Some books have an editor instead of, or in addition to, an author. If the whole book is a collection edited by one person, that editor may take the author position, usually followed by a label such as ed. in parentheses or after a comma. If you are citing a single chapter in an edited book, the chapter author comes first, the chapter title next, and the editor and book title follow. This pattern appears in every major style, though the words and punctuation differ.

Translated works usually credit the translator after the title. Some styles put the translator in the author position only when the translation itself is the focus of your discussion. If the original publication date matters to your argument, several styles let you include it in addition to the date of the edition you used. Check how your style handles it.

Editions matter because page numbers and text can change between them. If your copy states a second, revised, or later edition, record that. In-text page references only make sense for the edition you read. If you used the first edition, many styles omit the edition statement entirely.

Authors, groups and missing information

Books with several authors follow a rule about how many names to list. Styles differ on where to cut the list and replace the rest with et al. In-text citations often shorten sooner than the reference list does. Look up the current threshold in your manual instead of relying on memory.

Some books are written by an organization, such as a government agency or professional association. In most styles, that organization takes the author position. If the publisher and the author are the same organization, some styles ask you to leave the publisher out and others ask you to repeat it. Confirm in your guide.

If a date is not given, use the placeholder your style recommends, and if no publisher is named, consult the manual. Avoid guessing. Electronic books often have location numbers rather than pages. Many styles accept a chapter number or section heading as a locator in that case, since location numbers differ between devices. If you are unsure, ask your instructor how to cite passages from an e-book.

Proofreading a book citation

A good final check takes only a minute. Compare your entry with the title page: are all the author names in the right order and spelled correctly? Is the title copied exactly, including the subtitle? Is the year the year of the edition you used? Is the publisher the actual publisher, not an imprint of a retailer?

Then check formatting. Titles of books are usually italicized, and capitalization depends on the style. Make sure initials, commas, and periods follow your manual. Add a hanging indent if the style asks for one, and order your list alphabetically, or by the order of citation if your style is numbered.

If you use a generator, check that it did not pull data from a different edition or add an unrelated subtitle. It is easy to accept the first result a search returns. Take the extra moment to confirm. And remember that the current style manual, or the person marking your work, always has the last word on details.

One more habit is worth building: record each book as you use it, not at the end. Note the page numbers of passages you quote or paraphrase while the book is open on your desk. Returning to a library copy weeks later, only to find it has been borrowed by someone else, is a very common and avoidable source of stress.
