What is APA?

APA is maintained by the American Psychological Association, the main professional organization for Psychologists in the United States.

In-Text Citations and Reference List

APA Style uses in-text citations that have two formats. You can cite your sources in-text by using parenthetical or narrative citations. For more guidance, including examples for exceptions, view the APA's information on the Author-date citation system. 


Parenthetical Citations 

  • Include the name of the author(s) and the date of publication in parentheses
  • If a specific fact or quotation is being cited, include the page number 
  • Can be included within a sentence or at the end

Examples

Frederick Douglass spoke to over 1,000 people in Winona, Minnesota in 1867 (Gannaway, 2008, p. 74).

"Douglass stood before a supportive audience of more than a thousand. It was his first visit to Minnesota (Gannaway, 2008, p. 74).

Narrative Citations

  • Include the author's surname in the text with the date in parentheses immediately following
  • You can also include the author's surname and date in the narrative, in this rare case, do not include parentheses 

Examples

Gannaway (2008) noted the details of Frederick Douglass's first visit to Minnesota in 1867.

In 2008, Gannaway noted the details of Frederick Douglass's first visit to Minnesota in 1867.

A reference list is required for APA Style Papers. For guidance on setting up your reference list and examples, view the APA's Reference list setup, Common Reference Examples, and Creating an APA Style Reference List Guide.


Reference List Basics

  • Your reference page starts on a new page immediately following your text 
  • Include References at the top of the page in bold and centered 
  • Type each reference as a single paragraph, justified to the left 
  • Alphabetize your references 
    • Usually this is done with the authors last name, but when a source has no author, you use the title
  • The reference list should have a 0.5 inch hanging indent, which makes the first line of each source flush left 
  • Double space the whole list 
  • DOIs or URLs may be blue and underlined or plain text with no underline
  • Ensure that you have an in-text citation and reference entry for all your sources 
  • Check that your page numbers are displayed in the top right corner
