Do You Underline Book Titles When Writing? The Complete Guide to Formatting Titles Correctly
One of the most common questions that surfaces in academic writing, journalism, and even casual creative writing is whether you should underline book titles or use another formatting method. That's why the answer, while seemingly simple, actually depends on several factors including the style guide you are following, the medium in which your writing is being published, and the type of work you are referencing. But understanding the correct way to format book titles is essential not only for maintaining professionalism but also for showing respect to the authors and publishers whose works you cite. This full breakdown will walk you through every detail you need to know about formatting book titles, so you never have to second-guess yourself again Less friction, more output..
The General Rule: Italicize, Don't Underline
In modern writing standards, the widely accepted rule is that book titles should be italicized, not underlined. When you type a book title in an essay, article, or report, you should place the title in italics to set it apart from the surrounding text. Here's one way to look at it: when referring to the classic novel by George Orwell, you would write 1984, not underline it or place it in quotation marks.
This convention applies to most printed and digital publications today. The practice of underlining was more common in the days of typewriters, where italics were difficult or impossible to produce. Plus, italicizing a title signals to the reader that the work is a standalone, complete piece — a full-length book, a film, a newspaper, or a long musical composition. With the advent of word processors and digital publishing, italic formatting became easily accessible, making underlining largely obsolete for this purpose.
Why Underlining Fell Out of Favor
To understand why underlining is no longer the standard, it helps to look at the historical context. In practice, as a workaround, they would underline book titles to indicate that the text was meant to be italicized. In the era of manual typewriters, writers did not have the ability to easily produce italic characters. Editors and publishers understood this convention and would manually convert the underlines to italics during the typesetting process Easy to understand, harder to ignore. That alone is useful..
Still, once word processing software like Microsoft Word and Google Docs became mainstream in the 1980s and 1990s, italic formatting became a standard feature. This eliminated the need for underlining as a substitute. Today, underlining a book title can actually be seen as a sign of outdated formatting knowledge. Some style guides explicitly discourage it, preferring that writers either italicize the title or, in certain contexts, use quotation marks Took long enough..
How Different Style Guides Handle Book Titles
Different style guides have their own specific rules for formatting titles, and it is important to follow the one required by your institution, publisher, or audience. Here is a breakdown of how the most commonly used style guides treat book titles:
MLA (Modern Language Association)
The MLA style, widely used in humanities and literature courses, requires that book titles be italicized. For example:
- To Kill a Mockingbird by Harper Lee
- Pride and Prejudice by Jane Austen
In MLA format, shorter works such as articles, poems, and short stories go inside quotation marks, while full-length books are italicized. This distinction helps readers immediately identify the type of work being referenced.
APA (American Psychological Association)
The APA style, commonly used in social sciences, also requires book titles to be italicized in the reference list and in the body of the text. The title should be in sentence case, meaning only the first word and proper nouns are capitalized. For example:
- The effects of trauma on adolescent development
- Thinking, Fast and Slow by Daniel Kahneman
Chicago Manual of Style
The Chicago Manual of Style is one of the most comprehensive guides for book publishing and editorial standards. It strongly recommends italicizing book titles and other standalone works. Chicago also provides detailed guidance on how to handle titles within titles, using quotation marks for shorter works nested inside a larger title.
AP (Associated Press) Style
The AP style, used primarily in journalism, takes a slightly different approach. Which means in AP style, book titles are placed in quotation marks rather than italicized. This is because AP style is optimized for news writing where italics may not render properly in all formats That alone is useful..
- "The Great Gatsby"
- "Sapiens: A Brief History of Humankind"
Understanding which style guide applies to your work is crucial. Always check your assignment guidelines or publication standards before deciding on a formatting approach Worth keeping that in mind..
When to Use Quotation Marks Instead
While italics are the default for book titles, there are situations where quotation marks are more appropriate. As noted, AP style uses quotation marks for book titles. Additionally, if you are referencing a shorter work — such as a chapter within a book, an article from an anthology, or a short story — you should use quotation marks rather than italics Simple as that..
Short version: it depends. Long version — keep reading.
Here is a simple rule of thumb to keep in mind:
- Italicize titles of full-length, standalone works: books, films, albums, newspapers, and television shows.
- Use quotation marks for titles of shorter works: chapters, articles, poems, songs, and short stories.
This distinction is consistent across most major style guides and helps create clarity for the reader.
Common Mistakes When Formatting Book Titles
Even experienced writers sometimes make errors when it comes to formatting titles. Here are some of the most common mistakes to avoid:
- Underlining in digital content — As discussed, underlining is outdated in most digital and print contexts. Use italics instead.
- Using both italics and quotation marks — Placing a book title in quotation marks and italicizing it simultaneously is incorrect. Choose one method based on your style guide.
- Inconsistent formatting — Switching between italics and regular text for the same title within a single document is confusing and unprofessional.
- Forgetting to capitalize properly — Most style guides require that major words in a book title be capitalized. Do not write the great gatsby; instead, write The Great Gatsby.
- Placing punctuation inside or outside the title incorrectly — Commas and periods that are part of the sentence go outside the italicized title, while question marks or exclamation points that belong to the title itself should be included within the italics.
Special Considerations for Handwritten and Informal Writing
While digital writing has standardized the use of italics, there are still situations where handwritten work or informal communication might call for underlining. If you are taking handwritten notes, writing on a whiteboard, or composing a letter by hand, underlining a book title is perfectly acceptable as a visual indicator of italics. Similarly, in informal digital communication such as emails or social media posts where italic formatting is unavailable, underlining can serve as a reasonable substitute Most people skip this — try not to..
On the flip side, for any formal or academic writing, always default to italics. This applies to essays, research papers, dissertations, blog posts, and published articles. Maintaining proper formatting reflects your attention to detail and your commitment to professional standards That's the part that actually makes a difference..
The Role of Book Title Formatting in SEO and Readability
If you are writing content for an online audience, proper title formatting also plays a role in readability and search engine optimization. When readers scan your content, italicized titles stand out visually, making your text easier to deal with. This improved readability can lead to longer engagement times
and potentially stronger trust in your content. Search engines do not rank content simply because a book title is italicized, but well-formatted text can make your article easier to read, scan, and understand Still holds up..
Clear formatting also helps prevent confusion when you mention multiple titles in the same paragraph. Here's one way to look at it: if you write about a novel, a film, and a song in one sentence, using the correct formatting makes it immediately clear which titles are standalone works and which are shorter works within a larger publication.
Practical Tips for Formatting Book Titles Correctly
To keep your writing consistent, use these simple guidelines:
-
Italicize full book titles
Example: The Hobbit, Pride and Prejudice, Educated -
Use quotation marks for shorter works
Example: “The Tell-Tale Heart,” “The Lottery,” “A Rose for Emily” -
Do not italicize subtitles unless your style guide requires it
In most cases, the subtitle is included in the same formatting as the title.
Example: Sapiens: A Brief History of Humankind -
Keep formatting consistent throughout the document
If you italicize a title the first time it appears, continue doing so every time it appears. -
Use italics for emphasis carefully
While italics can stress a word or phrase, they should not be overused. Book titles already provide a natural form of emphasis, so avoid italicizing every noun or phrase in your writing.
Examples in Context
Here are some examples showing how book titles should appear in sentences:
- She recommended Atomic Habits as one of the most useful self-improvement books.
- His favorite novel is One Hundred Years of Solitude.
- The class discussed the themes of To Kill a Mockingbird during Friday’s seminar.
- She quoted a passage from “The Road Not Taken” in her speech.
- His research paper includes a chapter titled “Memory and Identity in Modern Fiction.”
These examples show the difference between formatting a complete book and formatting a shorter work within a larger publication Not complicated — just consistent. Simple as that..
Differences Among Major Style Guides
Although most style guides agree on the basic principle, they may differ in a few details.

Example:
She analyzed the symbolism in “The Yellow Wallpaper” while comparing it to Frankenstein.
APA Style

Example:
The study referenced data from The Culture Code by Daniel Coyle.

Common Questions About Book Title Formatting
Should I underline a book title in Google Docs?
No. Think about it: in Google Docs and other digital writing tools, you should use italics rather than underlining. Google Docs supports italic formatting, so there is usually no reason to underline a book title.
Can I use bold for book titles?
Bold is generally not used for book titles in formal writing. But italics are the standard choice. Bold may be appropriate for headings, labels, or emphasis, but not for title formatting in essays, articles, or academic papers.
What if I cannot format the title?
If you are writing by hand or using a plain-text format that does not support italics, underlining is the traditional substitute. In casual digital writing, italics may also be represented with asterisks, such as The Great Gatsby Surprisingly effective..
Should movie titles be
be formatted? And this is because films are considered complete, standalone works. Movie titles are also italicized, following the same convention as book titles. Here's one way to look at it: in an essay, you would write Pulp Fiction or The Shawshank Redemption.
Similarly, television series are italicized, while individual episodes are placed in quotation marks. Take this case: you might discuss the cultural impact of The Sopranos, and then analyze a specific episode like "The Knight in White Satin Armor."
This consistent application of italics helps readers quickly identify the type of work being referenced. The underlying principle is to use italics for the container of a work and quotation marks for the work itself. A poem is a work contained within a book, an episode is a work contained within a series, and an article is a work contained within a journal or website.
To wrap this up, the rules for formatting titles are designed for clarity and consistency. On top of that, by italicizing books, movies, and TV series, and using quotation marks for shorter works like poems, articles, and episodes, you ensure your writing adheres to professional standards. Always check the specific style guide you are using, as minor variations can exist, but these general principles will guide you correctly in most situations Took long enough..
