Citing with Multiple Authors: A Guide to Proper Citation
Citing sources is a crucial aspect of academic writing, and when working with multiple authors, it can become even more complex. The American Psychological Association (APA), Modern Language Association (MLA), and Chicago/Turabian citation styles have different guidelines for citing sources with multiple authors. In this article, we'll break down the rules for each style, providing you with a comprehensive guide on how to cite with multiple authors.
APA Style: Citing with Multiple Authors
According to the APA Publication Manual (7th ed.), when citing a source with multiple authors, you should list the authors' names separated by commas. Here are the rules for APA style:
- For sources with up to 20 authors, list all the authors' names.
- For sources with 21 or more authors, use "et al." (meaning "and others") after the first 20 authors' names.
Example:

Smith, J., Johnson, K., Williams, D., Thompson, R., & Brown, T. (2020). The impact of climate change on ecosystems. Journal of Environmental Studies, 10(1), 12-20.
Example: et al.
Smith, J., Johnson, K., Williams, D., Thompson, R., Brown, T., Lee, S., Davis, J., & Taylor, G. (2020). The effects of social media on mental health. Journal of Psychology, 20(2), 30-40.
MLA Style: Citing with Multiple Authors
For MLA style, the guidelines for citing sources with multiple authors are slightly different. According to the MLA Handbook (8th ed.), you should list the authors' names separated by commas, and use the phrase "and" before the last author's name. Here are the rules:
- For sources with up to three authors, list all the authors' names.
- For sources with four or more authors, use "et al." (meaning "and others") after the first three authors' names.
Example:
Smith, J., Johnson, K., and Williams, D. (2020). The impact of climate change on ecosystems. Journal of Environmental Studies, 10(1), 12-20.
Example: et al.
Smith, J., Johnson, K., and Williams, D., et al. (2020). The effects of social media on mental health. Journal of Psychology, 20(2), 30-40.
Chicago/Turabian Style: Citing with Multiple Authors
For Chicago/Turabian style, the guidelines for citing sources with multiple authors are similar to APA style. According to the Chicago Manual of Style (17th ed.), you should list the authors' names separated by commas, and use the phrase "and" before the last author's name. Here are the rules:
- For sources with up to 10 authors, list all the authors' names.
- For sources with 11 or more authors, use "et al." (meaning "and others") after the first 10 authors' names.
Example:
Smith, J., Johnson, K., Williams, D., Thompson, R., Brown, T., Lee, S., Davis, J., Taylor, G., Martin, K., and Rodriguez, L. (2020). The impact of climate change on ecosystems. Journal of Environmental Studies, 10(1), 12-20.
Example: et al.
Smith, J., Johnson, K., Williams, D., Thompson, R., Brown, T., Lee, S., Davis, J., and et al. (2020). The effects of social media on mental health. Journal of Psychology, 20(2), 30-40.
