There are two different formats of in-text citation, parenthetical and narrative. Both formats require two elements:
Author's name
Year of publication
Parenthetical citations are the more commonly seen form of in-text citations for academic work. Both required reference elements are presented at the end of the sentence in parentheses.
E.g. (Belafonte, 2008).
Narrative citations The author's name will be separated from the date. The date must appear immediately after the author's name but in parenthesis.
E.g. Belafonte (2008).
