What should be italicized in an APA reference list?

In an APA reference list, the titles of books are indeed italicized. This is a key aspect of formatting in APA style, as it helps to distinguish the title of the book from other elements in the citation, such as the author’s name and the publication year. Additionally, italicizing book titles enhances readability and ensures consistency throughout the reference list.

While other elements, such as journal article titles, are not italicized but rather presented in plain text and in sentence case, the volume number of a journal is also italicized. It's important to note that specific formatting rules apply to different types of sources within APA style, and understanding these distinctions is vital for proper citation practices. In this context, selecting the book title as the answer highlights the formatting conventions specifically associated with book citations in the APA style.
