Book titles are Underlined if you are writing them by hand. However, underlining is no longer used unless your instructor specifically asked you. If you are typing, you italicize the book titles instead.
You underline book titles.
Book titles should be italicized, while shorter works like poems and short stories should be in quotation marks. Italics are preferred in typed work, replacing the outdated practice of underlining. Remember to follow capitalization rules by capitalizing significant words in the title.
