How To Use Et Al In Text Citation
Chicago manual of style cms.
How to use et al in text citation. For sources with one two or three authors list all author names in your in text citations whether footnotes or author date. The use of et al is the same in both styles. In apa 7 for a work with three or more authors list the first author and et al for all citations including the first citation unless doing so would create ambiguity. Note that this rule has changed from apa 6 guidelines on using et al which recommend listing all author names in the first citation up to five authors but then using et al for the second and subsequent citations. For sources with four or more authors use the first name followed by et al.
