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.
General Rules for APA Format. Authors should be alphabetized by the last name of the first author of each work. If you want to cite multiple articles by the same author, list entries in chronological order from earliest to most recent. If there is no author given, begin your citation with the name of the primary source/article.
