Italicize Titles of Published Texts, Lengthy Works, and Legal Cases
As a rule, you should italicize the titles of published works, but you should not italicize parts of published works, such as a poem within a book, or unpublished works. Some exceptions that should be italicized include lengthy works, such as a very long poem within a book and legal cases. Some exceptions that should not be italicized include titles of published short stories and titles of individual television shows. Works that are not italicized are typically placed in quotation marks. Some other exceptions that should not be italicized include long religious works, such as the Bible and the Koran, and easily recognizable texts, such as the US Constitution.
