APA Style 7th edition: Reference List Formats for Author(s)

This guide covers stylistics of writing, formatting, and citing in APA Style 7th edition

Reference List Examples

This section includes APA 7th ed. examples for citing author(s). We've included the majority of possibilities for sources that you might use in your research; however, there are likely some examples we're missing. If you don't find the example you need, please contact the ERC. 

The ERC strives to simplify the citation process for students by organizing information in one handy guide. Use your source information to replace each piece in the sample and you will have a solid citation. We call that "mirroring." 

Single Author

More Than Twenty Authors

List authors by last names and initials. Use commas to separate their names. After the first 19 authors’ names, use an ellipsis to represent the remaining authors’ names. End with the final author’s name, but do not place an ampersand before it. Make sure there are only twenty names listed in the citation.

Two Authors

Group Author

Corporations, government  agencies, etc. also provide resources. Treat the publishing organization the same as an author and format the citation as normal. Provide the full name of the group in your references list. You can use abbreviations within the text. For entries in reference works like dictionaries and encyclopedias are also considered works with group authors.
