Italicize Book Titles? Formatting Rules

Updated November 7, 2026

Yes, the title of a book should be italicized in most formal writing, including MLA, APA, and Chicago styles. This rule applies to full-length books, novels, anthologies, and other standalone publications; however, shorter works like chapters, poems, and articles are placed in quotation marks instead.

Why Italics? A Brief History

The practice of italicizing book titles has its roots in the early days of printing. When italic type was introduced in the 16th century by Venetian printer Aldus Manutius, it was used to set off text that was distinct from the main body—like introductions, notes, or quoted passages. Over time, italics became a standard typographic cue to signal that a word or phrase is a title, a foreign term, or a word used as a word. By the 19th century, most style guides had codified the rule: full works (books, journals, films) get italics, while parts of those works (chapters, articles, poems) get quotation marks.

How Italicization Works in Practice

In modern publishing, italics serve a clear function: they visually separate the title from the surrounding text without adding extra punctuation. For example, in a sentence like “I just finished reading Moby-Dick,” the italics tell the reader that Moby-Dick is a book, not a whale. The same logic applies to other standalone works:

• Novels: Pride and Prejudice, The Great Gatsby
• Nonfiction books: A Brief History of Time, The Immortal Life of Henrietta Lacks
• Anthologies and collections: The Norton Anthology of English Literature
• Journals and magazines: Nature, The New Yorker
• Films, plays, and long musical works: Citizen Kane, Hamlet, The Ring Cycle

In contrast, shorter works—such as a chapter titled “The River” or a poem like “The Road Not Taken”—are placed in quotation marks because they are parts of a larger whole. This distinction helps readers quickly understand the hierarchy of a reference.

How to Choose the Right Format

Choosing between italics and quotation marks depends on the type of work and the style guide you are following. Here are the key factors:

• Is it a standalone publication? If the work is published independently (a book, a film, a journal), use italics. If it is part of a larger work (a chapter, an article, a short story), use quotation marks.
• What does your style guide say? MLA, APA, and Chicago all agree on the general rule, but they differ on edge cases. For example, APA italicizes the titles of reports and dissertations, while Chicago places them in quotation marks. Always check your specific guide.
• Are you handwriting? In handwritten text, italics are impossible, so underlining is used as a substitute. This is now rare in digital writing but still appears in some academic contexts.
• Is it a sacred text? The Bible, the Quran, and other sacred works are typically not italicized; they are capitalized but left unformatted. This is a convention, not a strict rule, and varies by guide.

Common Problems and Misconceptions

One frequent mistake is italicizing the title of a short story or poem. For instance, writing “I read The Raven” is incorrect because “The Raven” is a poem, not a standalone book—it should be in quotation marks: “I read ‘The Raven.’” Another misconception is that italicizing a title is optional or a matter of personal preference. In academic and professional writing, it is a strict rule, and failing to follow it can cost marks or credibility. Additionally, some people confuse italics with bold or underline. Bold is used for emphasis, not titles, and underlining is only a handwritten substitute for italics. A third issue arises with titles that include another title, such as a book about a film: the larger work is italicized, and the smaller work within it is placed in quotation marks (e.g., The Making of “Citizen Kane”).

Comparing Style Guides: MLA, APA, and Chicago

While all major style guides agree on the core rule, they have minor differences:

• MLA (Modern Language Association): Italicizes book titles, journals, and films. Quotation marks for articles, poems, and chapters. No underlining.
• APA (American Psychological Association): Same general rule, but also italicizes the titles of reports and dissertations. Quotation marks for article titles and book chapters.
• Chicago Manual of Style: Uses italics for book titles and journals, but for some technical reports and dissertations, it recommends quotation marks. Chicago also allows underlining in certain manuscript contexts.

These differences are subtle, but they matter in academic publishing. If you are a student, your instructor’s guide takes precedence. If you are a professional writer, your publisher’s house style is the final authority.

Digital Writing and Italics

In digital writing, italics are easy to apply in word processors and content management systems, but they can be lost in plain-text environments like email or chat. In such cases, the convention is to use asterisks or underscores (e.g., *Moby-Dick* or _Moby-Dick_) to indicate italics. On websites, HTML uses the tag or the tag, though is semantically for emphasis. For titles, is more appropriate because it is purely presentational. In social media posts, where formatting is limited, some people use quotation marks instead, but this is a compromise, not a rule. If you are writing for the web, your style guide may have specific recommendations—for example, the AP Stylebook (used by journalists) actually recommends quotation marks for book titles, not italics, because italics can be lost in news wire transmission. This is a notable exception to the general rule.
