Helpful Tips:
DOI: If a journal article has a Digital Object Identifier (DOI) listed, you will always include this identifier in your reference as a URL. You will not have to include a different URL or the database from which you retrieved the article if a DOI is available. Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
Online Database: If you viewed a journal article in an online database and it does not have a DOI, the reference should be the same as the reference for a print version of the work. In other words, nothing after the page numbers will appear.
Website/Online: If an online work (not including academic research databases), provide the URL in the reference (as long as the URL will work for readers).
Print: If you viewed a journal article in its print format, be sure to check if it has a DOI listed. If it does not, your reference to the article would end after you provide the page range of the article.
Date: When possible, include the year, month, and date in references. If the month and date are not available, use the year of publication.
