1-2 authors: List all authors' last names and initials in the order they appear on the title page, separated by an ampersand (&).
* Example: Smith, J. A., & Jones, B. C. (2023). *Title of book*. Publisher.
3-20 authors: List all authors' last names and initials in the order they appear on the title page, separated by commas. Use an ampersand before the last author's name.
* Example: Smith, J. A., Jones, B. C., Davis, M. E., & Brown, K. L. (2023). *Title of book*. Publisher.
21 or more authors: List the first 19 authors' last names and initials, followed by an ellipsis (...) and then the last author's name.
* Example: Smith, J. A., Jones, B. C., Davis, M. E., … Brown, K. L. (2023). *Title of book*. Publisher.
In-text citations:
* For all numbers of authors: Use the same format as the reference list entry (i.e., all authors' names for 1-20 authors, or the first 19 and the last for 21+). However, for sources with three or more authors, after the first in-text citation you may use the first author's last name followed by "et al." (and others).
* Examples:
* First citation (3+ authors): (Smith, Jones, Davis, & Brown, 2023)
* Subsequent citations (3+ authors): (Smith et al., 2023)
Remember to replace the bracketed information with the actual information from your source. Also, ensure your italics are correctly applied to the book title.
