"One of a number of standards addressing the need for more reliable resource identifiers is that of the Digital Object Identifier (DOI). A DOI is a unique and permanent name assigned to a piece of intellectual property such as a journal article or book (or a component thereof), in any medium in which it is published. (The term “digital” refers to the identifier and not necessarily to the object.) A DOI consists of a prefix assigned by a DOI registration agency such as CrossRef and — following a forward slash — a name assigned by the publisher. " - [|Chicago Style Manual Online]

NOTE: A DOI is preferred to a URL. (Chicago Style Manual Online 2011, [|link])

But, DOIs/use of them don't seem to prevalant yet. Add them if the they are available; but include URL for consistency. - Phil

" My thought is the more information the better. The whole point of citations is to give the reader information on how to find the document. URLs change, but there are internet archives. DOIs are not in fact readily available to the average reader, but can provide useful information to those with library access. And for bibliometricians, DOIs can provide important information as well. " - Ryan

DOIs are not "generally readily available, so you end up with inconsistency within your biblio. I think the generally accepted approach has been to cite the URL and the day it was last accessed. " - Barbera
