NOTE: Journal titles which begin with BMC are online-only and like other online-only journals, they do not use issue numbers, and do not have page numbers.
- For one article:
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:
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 by entering number here:

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).
Web page: Individual person(s) as author(s) (note capitalization of proper names, & when individuals to also include name of website)
- 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:
