Note: This is an answer only for citing within an appendix. If you are looking for information on how to cite an appendix you have created within the body of your text, please follow this link. 

Quick answer

• Use parenthetical in-text citations in your appendix
• Include all sources cited in your appendix in your larger alphabetical References section

Answer with explanation

The APA Publication Manual does not give explicit direction on how to cite external sources that are used within appendices. However, APA style favors the idea of keeping all sources cited in a single reference list. A good practice would be to cite your source information in your appendix with an in-text parenthetical citation, like you would in the body of your paper, and include the source in the alphabetical list with everything else in your References section. With a grey area like this, where the manual does not have explicit direction, it is often a good idea to check in with your instructor to ensure that your approach will align well with their expectations.
