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.
Explanation: When there is no author move the title to the author spot. If the title is a book or webpage, italicize title and end with a period. Do not italicize title if a journal article or book chapter. Follow title with publication date and publication information.
