Overview and Purpose
The Modern Language Association (MLA) style is widely used in the humanities for documenting sources. This guide explains how to cite books in MLA format, focusing on guidance commonly referenced from the Purdue Online Writing Lab (OWL). Accurate book citations support credibility, enable verification, and help avoid plagiarism. The information here reflects core, long-standing MLA principles that remain relevant across academic contexts and publication formats.
What Is an MLA Book Citation?
An MLA book citation is a structured list of elements that identifies a book and shows where it was found. In MLA, the citation appears in two places:
- In-text citations, which point readers to the full entry.
- The Works Cited list, which provides complete details for each source.
The basic structure emphasizes the author, the book title, publication details, and container information when applicable. The goal is to give readers enough information to locate the exact version you used.
Core Components of an MLA Book Citation
For a print book with one author, the core elements in the Works Cited entry follow this order:
- Author’s Last Name, First Name.
- Title of the Book in Italics.
- Publisher,
- Publication Date.
Use title case for the book title and end the entry with a period. If there are two authors, list the first in reverse order and use “and” before the second. For three or more authors, list the first author followed by “et al.”
Author Names
Names are formatted as Last Name, First Name, with a comma separating them. Include a period after the name. Middle names or initials follow the first name and are separated by a space.
Italicization and Punctuation
Books are italicized. Capitalize major words in the title and subtitle. Use commas to separate components and a period at the end of the entry. Consistent punctuation helps readers parse the citation quickly.
Works Cited Examples by Common Scenarios
The following table summarizes standard MLA book citation formats for typical situations.
| Scenario | Works Cited Format | Example |
|---|---|---|
| One author, print book | Last, First. Title. Publisher, Year. | Frank, Anna. The Data Lens. Clearview, 2019. |
| Two authors | First Last and First Last. Title. Publisher, Year. | Rivera, Carlos, and Dana Liu. Urban Patterns. Metro Press, 2021. |
| Three or more authors | First Last, et al. Title. Publisher, Year. | Cho et al. Digital Methods. Sage, 2020. |
| Editor of a book | Editor First Last, editor. Title. Publisher, Year. | Singh, Rani, editor. Modern Archives. Archival Press, 2017. |
| Edition other than first | First Last. Title. Edition ed., Publisher, Year. | Byrne, John. Applied Ethics. 2nd ed., Broadview, 2018. |
| Translator named | Author First Last. Title. Translated by First Last, Publisher, Year. | Dostoyevsky, Fyodor. Notes from Underground. Translated by Richard Pevear, Norton, 2022. |
| Book with no author | Title. Publisher, Year. | The Structure of Scientific Revolutions. Univ. of Chicago P, 2012. |
In-Text Citations for Books
In MLA, in-text citations point to the author’s last name and the page number(s) from which the quoted or paraphrased material comes. Place the citation at the end of the sentence, before the period, in parentheses.
- Single author: (Smith 45)
- Two authors: (Johnson and Lee 78)
- Three or more authors: (Chen et al. 102)
If the author’s name is mentioned in the sentence, include only the page number in parentheses. For books without page numbers, such as many online editions, use an alternative locator if available, or rely on paragraph numbers when provided.
Citing Books in an Online Container (e.g., Ebook Platforms, Library Databases)
When a book is accessed through a website or database, include the container title in italics, followed by the publisher or sponsor and a comma. Then list the format (e.g., Kindle, EPUB). If the work is more generally available online, include the URL or DOI at the end, omitting “http://” or “https://” unless special characters are required.
The author and book title remain the same as for print. The publication information may include both the original publisher and the platform. Use the version or edition you consulted.
Cross-Format Guidance and Common Pitfalls
Several issues frequently affect book citations:
- Punctuation: Over- or under-punctuation can confuse readers. Follow the standard pattern of period-comma-period and end with a period.
- Italicization: Only titles of independently published works, such as books, are italicized. Article or chapter titles are placed in quotation marks.
- Edition: Always note if you are using a second or later edition, and cite accordingly.
- Access date: In MLA (9th and 8th editions), publication date is typically required; an access date is only needed when the content is likely to change or when your instructor requests it.
Reliable Sources and Further Reading
MLA style is periodically reviewed, but core book citation practices remain stable. For the most authoritative and up-to-date guidance, consult the official MLA resources and the Purdue OWL MLA guide. If your discipline or publication adds supplementary conventions, check with your institution or publisher. Using consistent, verifiable citation practices supports clarity and long-term reference value.
