How should the title of a book be formatted in the reference list?

The title of a book in the reference list is correctly formatted by being italicized and written in sentence case. This means that only the first word of the title, the first word of any subtitle, and any proper nouns are capitalized, while all other words remain in lowercase.

Using italics distinguishes the book title from other elements in the reference, such as the author's name and the publication details. This formatting aligns with APA style guidelines, which prioritize clarity and consistency in academic writing. By adhering to these rules, readers can easily recognize the titles of works being cited, contributing to a well-organized and comprehensible reference list.
