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.
In short, a title you would italicize within the body of a paper will also be italicized on a reference page. However, a title you'd place in quotation marks within the body of the paper (such as the title of an article within a journal) will be written in normal lettering and will not be in quotation marks.
