Ordering of entries: Arrange in alphabetical order by first author's last name; then in chronological order, earliest items first; then in alphabetical order by title. List all single-author entries before multiple-author entries beginning with the same author's name. Do not number entries.
Spacing: Double-space both within and between entries.
Indentation: Indent the first line five to seven spaces or one default tab (approximately one-half inch). Note: This is the APA's specification for manuscripts submitted for its publications. Before formatting a final draft, consider whether your instructor or other audience prefers a different indentation. Materials actually published by the APA, for example, have a hanging indentation--that is, the first line of each entry is flush left and the subsequent lines are indented.
