No. Italicize book titles now; underline only when italics are not possible.
If you have wondered should you underline a book title, you are not alone. I have edited papers, blogs, and legal memos for years.
I will show you clear rules, easy examples, and edge cases. Keep reading to learn what works in school, media, and the web today.
What the major style guides say?
If you ask, should you underline a book title, major guides agree. Use italics for published book titles in most modern writing. Underlining is a legacy choice from the typewriter era.
Here is the short version from trusted manuals many editors use:
- Chicago Manual of Style: Use italics for book titles in text. No underlining.
- MLA Handbook: Use italics for books. Underline only if italics are not available.
- APA Publication Manual: Italicize book titles in text and in references. No underlining.
- AP Stylebook: Put book titles in quotation marks in news copy. AP does not use italics.
- The Bluebook and legal style: Prefer italics. Some courts still accept underlining, but italics are the norm.
These guides align on one point. Underlining is a fallback. Italics are clear and standard in print and online.
When is underlining still okay?
You may still ask, should you underline a book title, if you write by hand or in plain text. In a few cases, yes. Use it when italics are not an option.
Use underlining only when:
- You write by hand for a timed test or form.
- Your tool does not support italics, like some plain text fields.
- Your teacher or editor gives a strict rule to underline.
- Your court or office style sheet still asks for underlining.
Note the limits. If your platform supports italics, use them. It is cleaner and more readable for most readers.
How to format book titles in different places?
People often ask, should you underline a book title in an email or blog post. Use italics if your platform can show them. If not, use quotation marks as a stopgap, or underline in handwriting.
Follow these simple, real-world rules:
- Academic papers: Italicize book titles in the text. Follow APA, MLA, or Chicago.
- Reference lists: APA uses sentence case for book titles in references, in italics. MLA and Chicago use their own rules. Check your guide.
- Blogs and websites: Italicize book titles. Use the em tag in HTML for accessibility.
- Social posts: If italics are not easy, use quotes for clarity. Keep it short.
- Email and plaintext: Use quotes if italics are not possible. Underline only in rare cases.
Examples:
- I loved The Great Gatsby.
- In APA reference style: Fitzgerald, F. S. (1925). The great gatsby. New York, NY: Scribner.
Special cases and edge rules
This is where many writers slip and ask again: should you underline a book title. Some works do not take italics or quotes. Others have mixed parts that change the format.
Keep these edge rules in mind:
- Sacred works and reference books: Bible, Quran, and some dictionaries are set roman. No italics or quotes in many guides.
- Series and sets: Italicize the series title. Capitalize volume numbers as shown by the publisher.
- Chapters and parts of books: Use quotation marks for a chapter within a book. Do not italicize the chapter title.
- Foreign titles: Keep the original title in italics. Provide an English gloss in parentheses if needed.
- Ebooks and audiobooks: Still treat the work as a book. Italicize the title. Note the format only in references when asked.
Common mistakes and how to fix them
Writers often wonder should you underline a book title when stuck in a deadline. Small slips can unhinge a clean draft. Fix them fast with these checks.
Watch out for:
- Using quotation marks for book titles in academic work. Swap to italics.
- Mixing italics and underlines in one document. Pick one standard.
- Dropping italics when a title ends a sentence. Keep the italics, then add the period.
- Capitalization errors. Follow title case in text. Follow your guide in references.
- Inconsistent platform use. Your PDF, web page, and email should all match your style rules.
Quick checklist before you publish
If your brain asks should you underline a book title at the last minute, run this list. It will save time and edits.
- Check your target style guide. APA, MLA, Chicago, AP, or house style.
- Ask if italics are supported. If yes, use them for books.
- Keep parts straight. Books in italics, chapters in quotes.

- Stay consistent across the whole piece.
- Proofread out loud. You will catch stray quotes or missed italics.
- Confirm any teacher, editor, or court rules before you submit.
My experience as an editor and teacher
Early in my career, I kept asking myself, should you underline a book title in student papers. I learned fast that most errors came from mixed rules, not carelessness. Once I set one clear standard, grades and clarity rose.
In newsroom work, we used AP. People still asked, should you underline a book title here. The answer was simple.
We put book titles in quotes, because AP does not use italics. That choice fit the medium. On the web and in journals, I switch to italics. The key is to match the audience and the style sheet every time.
