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.
Major levels (highest level) titles in your APA title are centered on your paper. They should be formatted in boldface and the important words of the heading should be capitalized. The title page is considered the first page of an APA paper. The second page will be the page containing an abstract. Again, the abstract is a main section, so the heading should be set in boldface and centered on your paper. Note that the first line of an abstract is not indented.
