The examples below follow the Publication Manual of the American Psychological Association, 6th ed., 2010 (APA-M). Correct spacing, use of italics, and punctuation are essential. APA style requires double-spacing throughout the paper, including the Reference List page (APA-M, p. 229). The first lines of paragraphs should be indented 5 to 7 spaces. For additional examples, see APA-M, pp. 228-231. Sample pages of a completed paper appear on pages 41-59 of the APA-M.
See pages 92 and 170-174 of the APA-M for information about direct quotations. Author-date citations, placed within the text, replace footnotes or endnotes. Two examples:
Martin (1984) urges roommates to settle differences...
In her list of rules for roommates (Martin, 1984)...
If a citation you need is not illustrated here, find the APA Publication Manual in the reference section.

APA style reference pages are double-spaced throughout and use “hanging indent” format, meaning that the first line of each reference is set flush left and subsequent lines are indented. See the APA Citation Guide PDF for examples of correct spacing and indenting.
