Citing sources correctly is crucial for academic integrity. When dealing with multiple authors in APA style, the rules change slightly depending on the number of authors and the source type. This comprehensive guide will walk you through the process, ensuring you always cite correctly.
Understanding APA's Multiple Author Citation Rules
The APA style manual offers specific guidelines for citing sources with multiple authors. The key difference lies in how you present the authors' names in your in-text citations and your reference list.
In-Text Citations:
-
Two Authors: Always list both authors' last names every time you cite the source. Use the ampersand (&) instead of "and" to connect their names.
Example: (Smith & Jones, 2023)
-
Three or More Authors: For sources with three or more authors, cite only the first author's last name followed by "et al." (meaning "and others") in your in-text citations. This applies to the first and subsequent citations.
Example: (Smith et al., 2023)
-
Parenthetical Citations: Place the citation immediately after the information you are referencing, usually at the end of the sentence or clause.
Reference List Entries:
The rules for your reference list are slightly more detailed:
-
Two Authors: List both authors' last names and initials in the order they appear on the source.
-
Three to Twenty Authors: List all authors' last names and initials in the order they appear on the source, separating each name with a comma.
-
Twenty-One or More Authors: List the first 19 authors' last names and initials, followed by an ellipsis (...), and then the last author's name.
Examples:
-
Two Authors:
- In-text: (Smith & Jones, 2023)
- Reference List: Smith, J. A., & Jones, B. C. (2023). Title of work. Publisher.
-
Three Authors:
- In-text: (Smith et al., 2023)
- Reference List: Smith, J. A., Jones, B. C., & Williams, D. E. (2023). Title of work. Publisher.
-
More Than Twenty Authors:
- In-text: (Smith et al., 2023)
- Reference List: Smith, J. A., Jones, B. C., Williams, D. E., ... , Ziegler, P. Q. (2023). Title of work. Publisher.
Common Mistakes to Avoid:
- Inconsistent Author Listing: Maintain consistency in how you list authors throughout your paper—both in your in-text citations and the reference list.
- Incorrect Use of "et al.": Remember, "et al." is only used for three or more authors in in-text citations.
- Missing Publication Information: Ensure you include all necessary publication details in your reference list, such as the year, title, and publisher.
- Incorrect Formatting: Pay close attention to punctuation and spacing—following APA's precise formatting rules is essential.
