Articles - incl. APA change to DOI format on March 1, 2017 (different from 6th ed.)

How to find assigned DOI

For one article:
1. Check the first page of article (usually in smaller print near journal logo, copyright, or near author email address).
2. If not on article, check database record/abstract (sometimes labeled as DOI). CINAHL began adding DOI's in 2009.
3. If DOI does not appear on either article or in database, search the Cross/Ref DOI Lookup using article author/title

For list of references:
1. Create an account at Cross/Ref. After you submit your request, you will receive an e-mail. Please click on the provided link to activate your account.
2. Next, go to Simple Text Query Form and enter your e-mail address, then copy & paste entire reference list into box. Click submit.

An individual DOI may be verified/searched:

Articles assigned DOI

NOTE: Journal titles which begin with BMC or other online-only journals often use document numbers instead of issue numbers, as in this example in volume 15: 15:366. However, do not use the document number in your reference; instead, provide the volume number followed by page numbers. See third example below.

Web Pages (incl. CDC & Mayo Clinic Staff)

  • (Informally Published or Self-archived Work, Manual, p. 212)

Individual web page

Since web pages and documents are similar to print, references to them include the same elements such as author, date, title, etc. Note that proper names and acronyms are capitalized. Date of retrieval is included because "the source material may change over time" (Manual, p. 192, and apastyle.org).

IMPORTANT NOTE: the web page title is not italicized because APA considers web pages informal publications. If the web page is also available as an online document/report (for example in PDF), please download that report, cite in-text appropriately, and use the online report format instead (click here to jump to those examples).

Note regarding citing an entire web site source

When discussing an entire web site (as opposed to a specific page on the web site), an entry does not appear in the reference list, but is cited within text as shown in the following sample sentence:
The International Council of Museums web site provides many links to museums, codes of ethics, and the museum profession (http://www.icom.org/).

Illustrations retrieved online

Photographs, drawings, etc. copied or adapted from a Web Page

Notes: APA Manual (p. 192) states: "Do not include retrieval dates unless the source material may change over time." Since web page content often changes, provide the date of retrieval. Also, if you must split the URL between two lines, do so before a slash, but do not split http://.

Following illustration title, insert type of medium in square brackets. Illustration types include diagram, photograph, painting, drawing, bronze sculpture, etc.
