How do you format a bibliography in APA Style®?
APA Style® calls for a list of references instead of a bibliography.
The requirements of a reference list are that all references cited in the text of a paper must be listed alphabetically by first author's last name in the list of references and that all references listed must be cited within the text.
A bibliography, however, typically includes resources in addition to those cited in the text and may include annotated descriptions of the items listed.
In general, the list of references is double-spaced and listed alphabetically by first author's last name. For each reference, the first line is typed flush with the left margin, and any additional lines are indented as a group a few spaces to the right of the left margin (this is called a hanging indent).
