The references list contains publication information for all sources that you have cited within your document, with two exceptions. Entire Web sites and personal communication, such as e-mail messages, letters, and interviews, are cited only in the text of the document.

Begin the list on a new page at the end of the document, and center the title “References” at the top. Organize the list alphabetically by author (if the source is an organization, alphabetize it by the name of the organization; if the source has no known author, alphabetize it by title). All of the entries should be double-spaced with no extra space between entries. Entries are formatted with a hanging indent: the first line is flush with the left margin, and subsequent lines are indented one-half inch. Only the initial word and proper nouns (names of people, organizations, cities, states, and so on) in a source title and subtitle are capitalized.

In longer documents, a references list may be given at the end of each chapter or section. In electronic documents that use links, such as Web sites, the references list is often a separate page to which other pages are linked.

For examples of references lists in APA style, see Chapters 6, 7, and 8.
