if a source has three or more authors, you should use “et al.” in your in-text citation.
For example, if you are citing a source with three authors, your in-text citation would include the first author’s last name, followed by “et al.” and the year of publication:
Citations at the end of a sentence are placed in parentheses: (Jones, et al., 2010)
Citations can also follow a narrative format and be integrated into a sentence: Jones et al. (2020) posit…..
It is important to note that “et al.” is always used in the in-text citation, even if you include all of the authors’ names in the reference list. This is to avoid cluttering the text with long lists of names and to give credit to all of the authors of the source.
