Examples of Citing Books

Use the Reference style for items listed alphabetically at the end of the research paper. The In-Text style is for the same items referred to in the body of the paper. Include page numbers in the In-Text style only when quoting from a source. When paraphrasing from a source, omit the In-Text page numbers. (7th edition omits publisher location.)
