Digital written-word sources
Updated guidelines for citing digital resources are maintained at the APA’s Web site (www.apa.org).
24. article from an online periodical. Give the author, date, title, and publication information as you would for a print document. Include both the volume and issue numbers for all journal articles. If the article has a digital object identifier (DOI), include it. If there is no DOI, write Retrieved from and the URL for the periodical’s home page or for the article (if the article is difficult to find from the home page). For newspaper articles accessible from a searchable Web site, give the site URL only.

25. article from a database. Give the author, date, title, and publication information as you would for a print document. Include both the volume and issue numbers for all journal articles. If the article has a DOI, include it. If there is no DOI, write Retrieved from and the URL of the journal’s home page (not the URL of the database). The source map on pp. 476–77 shows where to find this information for a typical article from a database.

Include all of the following information that you can find: the author’s name; the publication date (or n.d. if no date is available); the title of the document, italicized; and Retrieved from and the URL. Provide your date of access only if an update seems likely. The source map on pp. 480–81 shows where to find this information for a report from a Web site.

31. email message or real-time communication.Because the APA stresses that any sources cited in your list of references be retrievable by your readers, you should not include entries for email messages, real-time communications (such as IMs), or any other postings that are not archived. Instead, cite these sources in your text as forms of personal communication (see p. 462).
32. online posting.List an online posting in the reference list only if you are able to retrieve the message from an archive. Provide the author’s name, the date of posting, and the subject line. Include other identifying information in square brackets. End with the retrieval statement and the URL of the archived message.
