Writers must correctly acknowledge the sources of borrowed words and ideas when writing research papers in order to avoid charges of plagiarism, which, apart from the ethical concerns, can also have serious consequences ranging from loss of credit on the assignment to expulsion from school. Citing an essay within a book requires proper formatting both within the text of your paper and on the References page.
APA in-text citations, whether they appear in signal phrases or parenthetical citations, typically include the author's last name and the year of publication. As explained in the sixth edition, second printing of the "Publication Manual of the American Psychological Association," when you cite an essay within a compilation, you should give the last name of the author of the essay in the citation along with the year the book was published with a comma between. For an article written by Kelly James appearing in a book published in 2011, the citation would appear like this: (James, 2011).
The References page entry begins with the information that appears in the citation, so start with the author of the essay, the last name followed by the first initial with a comma between. After a period, you should place the publication date, in parentheses, ending with a period. The title of the essay appears next followed by a period. Capitalize the first word but no others except proper nouns, and you should not use italics or quotation marks around it. Next write "In" (without the quotation marks) and give the editor, first initial followed by last name. Use "&" (without the quotation marks) between them if you have more than one. Put (Ed.) and a comma to indicate this is an editor, and then give the title of the book, italicized. The page numbers for the essay appear next, in parentheses, after "pp." (without the quotation marks). After a period, the location, a colon and the company appear for print sources. Such an entry might look like this: James, K. (2005). The article's title. In D. Evans & E. Raines (Eds.), The name of the compilation (italicized) (pp. 133-152). New York: Penguin.
Web pages give "Retrieved from" (without the quotation marks) and the URL instead of the publisher details.
