Q. How do I cite a work by one author in APA Style?

APA 6th Edition 

When citing a resource by one author, provide the last name of the author or the corporate/group author's name and the date of publication at the appropriate point. To decide the placement of the citation, “if the name of the author appears as part of the narrative . . . cite only the year of publication in parentheses. Otherwise, place both the name and the year, separated by a comma, in parentheses” (American Psychological Association, 2010, p. 174). Remember that the page or paragraph number is also required for a direct quotation; see "What is an in-text citation?" for more information.

Examples

• Lastname (year of publication) noted that, "quotation" (p./para. #).
  • e.g., Johnson (2010) noted that, "quotation" (p. 4). 
• Signal phrase, “quotation” (Lastname, year, p./para.  #). 
  • When considering this issue, "quotation" (Royal Roads University, 2013, para. 7).

APA 7th Edition

Citations for an individual author should include the last name of the author and the date of publication either within a sentence or in parentheses (American Psychological Association, 2020, p.266). Citations for a group or corporate author will use the title of the organization or group as the author name, followed by the publication or copyright date for the resource (American Psychological Association, 2020, p.262). For example:

• Parenthetical citation: (Powers, 2018)
• Narrative citation: Powers (2018)
