How to find assigned DOI
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:
Create an account at Cross/Ref.
Next, enter your e-mail address, then copy & paste entire list into Simple Text Query box (takes a few minutes).
An individual DOI may be verified/searched by entering number here:

Informally Published or Self-archived Work (Manual, p. 212)Entire Web site
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:Individual web page
The International Council of Museums web site provides many links to museums, codes of ethics, and the museum profession (http://www.icom.org/).
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).Web page: Persons as authors

Photographs, drawings, etc. copied or adapted from a Web PageNotes: 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://.
