What is a DOI?
"A digital object identifier (DOI) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the Internet." -American Psychological Association (APA)

Because citation databases index each reference, it is possible to search these cited references. One can follow a particular cited reference, or cited author, forward in time to find more current articles that have also cited that author or work.
Go to A-Z Database List, select Indexed from the All Database Types dropdown, see example .
