Citation Help: APA

APA Style, 7th Edition

Cite in two places: in the text, and at the end of the paper.

  • Parenthetical in-text citations (author, date) appear at the end of a sentence before the period. Narrative in-text citations have the author name appear in running text and the date in parentheses immediately after - author (date). 
  • A References page at the end of the document has full citations in alphabetical order formatted with a hanging indent. 

Every in-text citation must correspond with a full citation on the References page, and vice versa. You can't include a source in your references list if you don't also cite it in your paper.
