APA guidelines stipulate rules for punctuation, tables, headings, statistics and citations. Citing your sources according to APA style helps you avoid plagiarism and boost your paper's credibility. When you cite or mention a book in a paper, you should italicize the title. Citations of books in your Reference List should begin with the last name of the book's author, then the author's initials.
Note that in APA 5th Edition style, the following rules apply for the reference: 1  For reference books, which includes encyclopedias, dictionaries, and glossaries, the book title is preceded by the word In. 2  It is not italicized, but the book title following it is.
