Digital Object Identifier (DOI)

Since 2000 there has been an effort to assign everything that exists in the digital world, e.g. online articles, with a unique number called a Digital Object Identifier or a DOI.  The DOI is unique, permanent, and persistent. It remains the same despite changes in URL's or permanent removal from the Internet.

In APA and AMA citation styles, use the DOI in citations whenever one is listed.
