DOI
versus websites.
Whenever
you are citing from an electronic document add the digital object identifier
to the citation if there is one. Digital Object Identifier (DOI)
is a number that is unique to a document. APA 6th edition suggests
that you use the DOI whenever possible instead of the website address. DOIs can
usually be found in the journal record in the database you download it
from. Sometimes they will be listed on
the pdf document itself.
