AGEN 332-Engine Dynamics Seminar: Citing Souces in APA

APA Style

What is APA Style?

APA Style is an editorial style developed by the American Psychological Association and used for written materials in the social and behavioral sciences. APA Style requires you to cite the sources you have used in two places: the in-text citation and as part of your reference list at the end of your paper.

How do I Format In-Text Citations?

  • Arrange your citations alphabetically by author’s last name
  • Arrange anonymous (no author) works by the first significant word in the title
  • Double-space between each entry
  • Indent the second line of each entry (a hanging indent)
