APA Styling – Reference Lists

Reference List: General Overview

  • The reference list:
    • appears at the end of the paper, and is the last portion of the “Main Body” of the paper
    • provides the full information for all references that were cited within the paper
    • begins on a new page
    • is labeled References in the center at the top of the page – do not bold, underline, italicize, or use quotation marks
  • All font, spacing, and margins are the same as the body of the paper.
  • When including page numbers, remember the following: 
    • “p.” indicates that only one page was referenced
    • “pp.” indicates that multiple pages were referenced
  • Utilize hanging indentation: All remaining lines after the first line of each entry are indented ½ inch from the left margin.
  • Reference lists are always alphabetized.

Reference List: How to Cite Authors

  • Authors’ last names always come before their first, separated by a comma
    • Only the author’s last name is fully spelled, but the first and middle initial (if provided) are used.
                 Example: Doe, J.A. or Doe, J.
  • Only list up to seven authors; if the work being referenced has more than seven authors, list the first six followed by “et al.”
    • Example (seven authors total):
      First, A.B., Second, A., Third, B.C., Fourth, E., Fifth, F., Sixth, G., & Seventh, A. (2014).
    • Example (more than seven authors):
      First, A.B., Second, A., Third, B.C., Fourth, E., Fifth, F., Sixth, G., et al. (2014).
  • If the same first-author is cited multiple times, list entries in chronological order from earliest to most recent. Below is an example:
          Doe, J. (2000).
          Doe, J. (2014).
  • Note: Sometimes an organization, such as the American Psychological Association, is the author of a work being referenced. Include the entire name of the organization in place of the author’s name.
            American Psychological Association. (2000).

Reference List: Journals and Periodicals

  • How to create a reference from a journal/periodical:
    • Use the reference guidelines for authors as already stated previously: Last name, first initial.
    • Publication year in parentheses and a period.
    • The title of the article.
      • Only the first word of the title and proper nouns are capitalized.
  • The title of the journal/periodical (italicized).
  • Volume number (italicized).
  • Issue number.
  • Page(s).
  • If a DOI has been assigned, include at the end.
    • If no DOI was assigned, but the article was accessed online, use the URL in place of the DOI.
           Author, A., Second, B.B., Third, C.C., & Fourth, D. (Year of publication). Title of article. Title of Periodical or Journal, volume number(issue number), pages. DOI or URL.
    • Sometimes, a reference may be from a magazine or newspaper, in which the following reference style is utilized:
           Author(s). (Year of publication, Month[spelled out] day). Title of magazine/newspaper article (only the first word is capitalized). Magazine/newspaper title, volume number, page(s). 
    • If a review is being referenced (i.e. a review of a book), the following format is used:
           Author(s). (Year of publication). Title of the review [Review of the book Title of the book, by Author(s)].Journal or Periodical Title, volume number, pages.

Reference List: Books and Printed Sources

  • In a reference list, books are referenced in the following basic format:
    Author(s). (Year of publication). Title of book: Subtitle if applicable.
    Location: Publisher.
  • The location is the city and state (two letter abbreviation without periods).
    • Example: New York: NY.
  • If the referenced work was republished, both dates should appear in reference.
  • If a later edition of a book is used, be sure to include the edition that is being referenced, not the first edition. Below is an example: 
    Author(s). (Year of publication). Title of book (Number ed.). City, State: Publisher.
  • If only an article or chapter is being referenced from an edited book, follow this format:
    Author(s). (Year of publication). Title of chapter. In A. Editor & B. Editor (Eds.), Title of book  (pages of chapter or article).
    Location(State is abbreviated): Publisher.
  • If a reference is being cited from a multivolume work, use the following format:
    Authors(s). (Ed.). (Year of publication). Title of work (Vols a-b). Location        
             (State): Publisher.
  • If a reference is being cited from an entry in an encyclopedia, the format will go as follows:
    Author(s). (Year of publication). Title of encyclopedia entry. In Title of Encyclopedia. (Volume 
              number, page[s]). City of publication, State of publication (Two letter abbreviation):     
    Publisher.
  • Sometimes work is discussed in a secondary source (i.e. an article that is cited within another article), which holds different formats for the in-text citation and the citation in the reference list. Give the secondary source in the references list, but in-text, name the original work, and cite the secondary source in parentheses. Follow this example:
    • There is Article A by Doe, J. (1998), and Article B by Smith, A. (2004). Article A is cited in Article B, and the information from Article A is being used in the paper.

      For the in-text citation: Note Article A, but cite Article B:
            In Doe’s (1998) study (as cited in Smith, 2004),…

      For the reference list: List the source the work was discussed in:

Smith A. (2004). Title of work. Title of Journal, volume number, pages.

  • It is possible to cite a dissertation, but as a rule of thumb, this should not be a regularly used source.
      • To cite a published dissertation:

Author. (Year of publication). Title of dissertation (Doctoral dissertation). Retrieved from Name of
          database. (Accession or Order Number).

      • To cite an unpublished dissertation:

  • If a reference is being cited from a private organization, format the following way:

Name of Organization. (Year of publication). Title of document: Subtitle if
          applicable. (Ed.) City, state of publication: Author.
