What are the APA rules on appendices?
Please refer to pages 38 and 39 in the Publication Manual of the American Psychological Association (American Psychological Association, 2010) for a full description, but see below for appendix basics:
- "An appendix is appropirate for materials that are relatively brief and that are easily presented in print format" (p. 39).
- "If your manuscript has only one appendix, label it Appendix; if your manuscript has more than one appendix, label each one with a captial letter (Appendix A, Appendix B, etc.) in the order in which it is mentioned in the main text" (p. 39).
- "Each appendix must have a title. In the text, refer to appendices by their labels" (p. 39)
- "Like the main text, an appendix may include headings and subheadings as well as tables, figures, and displayed equations" (p. 39)
- "Begin each appendix on a separate page. Center the word Appendix and the identifying capital letters (A, B, etc., in the order in which they are mentioned in text) at the top of the page. Center the title of the appendix, and use uppercase and lowercase letters" (p. 39).
If you're struggling to decide what should appear in the body text versus in an appendix, think about whether or not your reader would find the information critical to understanding your discussion, or if the information is supplemental. In other words, is the information "need to know" or "nice to know"? If it's "need to know", include it in your body text; if it's "nice to know", an appendix is probably a good home for the information. If you're unsure, please check with your instructor/supervisor.
