APA Quick Guide

APA Style Format

Link to print-friendly version

One of the most important parts of writing a research paper is the documenting of the resources used. Accurate documentation is necessary to avoid any question of plagiarism. The vehicles for providing this documentation are the use of in-text citations (or parenthetical references) at the point in the paper where the information is presented and the creation of a References list at the end of the paper listing all of the resources used. This guide includes samples of in-text citations and citation entries from the APA's Publication Manual, 6th ed, 2010. 
See sample research paper.

The References list appears at the end of your paper, on its own page, with the title References (not bolded or underlined) centered at the top, and continuing the page numbers of the text.  A References list should include only the sources referred to in your text.

  • Begin each entry flush with the left margin and indent subsequent line(s) five spaces.
  • Double-space both within and between entries.
  • Book titles and journal names must be italicized.
  • Remember that all references cited in the text must be listed alphabetically by the first author's last name in the list of references. If author is unknown, alphabetize by the title.

ONLINE MAGAZINE AND JOURNAL ARTICLES

Many scholarly publishers have been assigning unique identifiers to each published article. The DOI (Digital Object Identifier) is an alpha-numeric code registered to each scholarly article in order to assign a persistent link to the article. The DOI has replaced the database name and URL in the list of references. Because the link is to the final version, do not include a retrieval date. Since DOI numbers are complex, copy and paste DOI into the reference. APA recommends that the DOI be included for print and online citations if available.

Where do I find a DOI?

  • It may be part of the citation or abstract of a record.
  • It may be found on the first page of an article, especially if in pdf format.
  • Use DOI Lookup.
  • Cut and paste a citation into CrossRef Simple Text Query.

Articles with DOI

Magnavita, J. (2008). Toward unification of clinical science: The next wave in the evolution of psychotherapy? Journal of Psychotherapy Integration, 18, 264-291. doi:10.1037/a1300490

Citation in text: (Jacobson, Mulick & Schwartz, 1995)


Articles without a DOI

If no DOI has been assigned, provide the home page URL of the journal, book or report publisher. If you are accessing through a database, you may need to do a web search to locate the URL. It is not necessary to include the name of the database. There is no period at the end of a reference citation ending with a URL.
