Start your reference list at the end of your paper on a new page separate from your essay's text. Center the word "References" without using special formatting, including quotation marks. Each source you cite in the text of your paper must have a corresponding reference list entry.
Order your reference list alphabetically by each source's first author's last name. Double-space all text in your reference list.
Type the first line of each entry up against the left margin. The APA style website states that you should indent the second and all subsequent lines "a few spaces to the right of the left margin" to create a hanging indent.
List entries with one author as follows.
