"In-text citations have two formats: parenthetical and narrative."
A narrative citation incorporates the author(s) into the text as part of the sentence.
A parenthetical citation presents citation information in parentheses. "A parenthetical citation can appear within or at the end of a sentence."
Narrative citation example:
Alexander (2018)
Parenthetical citation example:
(Alexander, 2018)
