In the author-year system, your references are listed on a separate references page in alphabetical order, using the last names of the authors, article title (if no author), or publisher name. The type should be double-spaced, lines should not be skipped between each reference, and a hanging indent of five spaces should be used after the first line of each reference. Always include the word "References," boldfaced, in the center at the top of the page.
