Are Book Titles Underlined Or Italicized

The short answer is that modern style guides universally recommend italicizing book titles, while underlining is considered an outdated practice reserved mostly for handwritten work or specific, legacy formatting requirements. If you are typing an essay, article, blog post, or formal paper on a computer, you should use italics. Understanding why this shift happened and knowing the few exceptions will save you from formatting errors that can make your writing look dated or unprofessional.

The General Rule: Italics for Major Works

In contemporary writing, the standard convention dictates that titles of major works—also known as standalone works—should be italicized. This category includes books, but it extends to other complete, independent creative works. When you italicize a title, you are visually signaling to the reader: "This is a complete entity published on its own.

Examples of works that take italics:

• Books: To Kill a Mockingbird, The Great Gatsby, Sapiens: A Brief History of Humankind
• Periodicals (Newspapers, Magazines, Journals): The New York Times, National Geographic, Nature
• Films and Movies: The Godfather, Parasite, Citizen Kane
• Television Series (the show as a whole): Breaking Bad, The Crown, Friends
• Plays (full-length): Hamlet, A Streetcar Named Desire, Hamilton
• Long Poems (published as books): The Odyssey, The Divine Comedy, Leaves of Grass
• Music Albums: Thriller, Rumours, Lemonade
• Video Games: The Legend of Zelda: Breath of the Wild, Elden Ring
• Artworks (Paintings, Sculptures): The Starry Night, Mona Lisa, David

If you are following APA (American Psychological Association), MLA (Modern Language Association), Chicago Manual of Style (CMOS), or AP (Associated Press) style, the rule is consistent: italicize book titles. There is virtually no major modern style guide that prefers underlining for typed manuscripts.

Why We Stopped Underlining: A Brief History

To understand the current rule, it helps to know the history. The practice of underlining book titles originated in the era of the typewriter and handwritten manuscripts Simple, but easy to overlook. But it adds up..

The Typewriter Limitation Standard mechanical typewriters lacked an italics key. They could produce bold text (by backspacing and typing over letters) and underlined text (by backspacing and hitting the underscore key), but they could not slant the font. Because of this, writers and typists adopted underlining as the manuscript instruction for the typesetter. When a manuscript went to a professional printer, the underlined text told the typesetter: "Set this in italics."

The Digital Revolution With the advent of word processors (WordPerfect, Microsoft Word, Google Docs) and desktop publishing, the technical limitation vanished. Every modern keyboard and software suite allows for instant italicization. Because the "instruction to the typesetter" is no longer necessary—the writer is the typesetter—the convention shifted. We now apply the final formatting (italics) directly, rather than the proxy markup (underlining) Most people skip this — try not to..

The Web and Accessibility Factor On the web, underlining carries a specific semantic meaning: it denotes a hyperlink. Underlining text that is not a link creates a poor user experience (UX) and accessibility issues. Readers instinctively try to click underlined text. Using italics for titles avoids this confusion entirely, making your digital content cleaner and more accessible.

The Exception: Handwriting and Specific Constraints

There is only one significant scenario where underlining remains the correct choice: handwriting.

If you are writing an essay by hand for an in-class exam, a standardized test (like the SAT or ACT essay portion, though many are digital now), or a physical letter, you cannot easily produce italics by hand. Think about it: attempting to handwrite slanted cursive for a title often looks messy and is hard to read. In these specific analog contexts, **underlining is the standard substitute for italics.

Some specific, rigid institutional style guides or academic departments may still request underlining in typed papers due to institutional inertia, but this is increasingly rare. Always check your specific assignment sheet or professor’s preference. If no preference is stated, default to italics.

Minor Works: Quotation Marks, Not Italics or Underlining

A common point of confusion is distinguishing between major works (italicized) and minor works (parts of a larger whole). Minor works are placed in quotation marks, never italicized or underlined Less friction, more output..

This distinction is crucial for clarity. The "container" gets italics; the "content inside the container" gets quotes.

Style Guide Nuances: AP vs. The Rest

While the major academic styles (MLA, APA, Chicago) agree on italics for books, the Associated Press (AP) Stylebook—the standard for journalism and news writing—has a notable divergence Took long enough..

AP Style does not use italics at all. Because news wire services historically transmitted plain text that couldn't support formatting like italics or bold, AP style dictates that book titles (and movie titles, song titles, etc.) should be enclosed in quotation marks.

• MLA / APA / Chicago: I read The Catcher in the Rye last summer.
• AP Style: I read "The Catcher in the Rye" last summer.

If you are writing a press release, a news article, or content for a media outlet that follows AP style, you must use quotation marks. For almost all other contexts—academic papers, business reports, novels, blog posts, marketing copy—italics are the standard.

Capitalization Rules: Title Case

Regardless of whether you italicize or use quotes (AP style), you must apply Title Case capitalization to the title. This means capitalizing the first word, the last word, and all principal words (nouns, pronouns, verbs, adjectives, adverbs, and subordinating conjunctions).

Do not capitalize:

• Articles: a, an, the
• Coordinating Conjunctions: and, but, or, nor, for, so, yet (usually under 4 letters)
• Prepositions: in, on, at, to, from, by, with, of (usually under 4-5 letters, though Chicago lowercases all prepositions regardless of length)

Examples:

• The Old Man and the Sea (Preposition "and" lowercased; article "the" lowercased)
• A Tale of Two Cities (Preposition "of" lowercased)
• Gone with the Wind (Preposition "with" lowercased in Chicago/MLA; often capitalized in AP if 4+ letters)
• Harry Potter and the Deathly Hallows

Pro Tip: The word "The" at the beginning of a title is

The word “The” at the beginning of a title is treated differently depending on which style guide you follow. In Chicago Manual of Style, when a title begins with “The,” it remains capitalized because the whole title is italicized rather than quoted. By contrast, AP Style calls for the leading “The” to stay lowercase even inside quotation marks, reflecting its broader preference for brevity in headlines and news copy. This distinction can affect headline readability—readers may instinctively look for a capital “T” as a cue for the start of a new section—but adhering strictly to your target audience’s conventions will keep your work consistent and unmistakably professional.

When a single‑word title appears alone—such as “Lost” or “Hamlet”—AP style requires quotation marks around the entire word, while MLA, Chicago, and other scholarly formats typically italicize the same word without any punctuation. , 1984), that numeral is set in parentheses and placed immediately before the title within quotation marks (“1984”). If a title contains a number (e.Subtitles are generally left out of italics or quotation marks unless they constitute a separate, distinct element; however, many publishers now treat the main title only, leaving the subtitle unaltered. Which means g. Take this case: the novel To Kill a Mockingbird is usually presented as “To Kill a Mockingbird,” whereas the accompanying subtitle “Nelle Harper Lee” would appear outside any markup Turns out it matters..

Handling multi‑part titles presents another layer of complexity. When a work has both a primary name and a descriptive element—such as Pride and Prejudice and Zombies—you should enclose each part in quotation marks and preserve internal capitalization according to the chosen style. Under AP, the full string stays in quotes, preserving the original capitalization; under Chicago, the entire quoted block retains its own capitalization, but you may optionally add parenthetical clarifications if needed. Conversely, if a title consists of several short phrases separated by commas, such as The Great Gatsby (1925), the year should remain outside the quotation marks, following the general rule that dates, numbers, and abbreviations do not require special treatment.

Foreign‑language titles pose additional considerations. Here's one way to look at it: Don Quixote (Spanish) remains “Don Quixote,” while Les Misérables (French) becomes “Les Misérables.Most style guides recommend keeping the original orthography, including diacritics, and applying the appropriate case rules to the Latin alphabet representation. ” When translating a title into English, you decide whether to retain the original form or adapt it; whichever choice you make, the capitalization and quoting conventions still align with the selected style That's the whole idea..

Finally, remember that style guides are living documents—they evolve to accommodate new media forms and digital publishing practices. While AP continues to favor quotation marks over italics for emphasis in news reporting, many online platforms automatically render italics through syntax highlighting, blurring the line between the two. Regardless of the medium, maintaining a clear, consistent approach safeguards against inadvertent errors and demonstrates respect for the reader’s expectations. By choosing one authoritative system and applying its specifics uniformly across every piece of writing, you ensure clarity, professionalism, and stylistic integrity throughout your body of work.
