ABSTRACT
Digital Object Identifiers (DOIs) have uses beyond reference linking and document identification, which are their current primary selling points. Due to their inherent stability, DOIs are well suited for creating deeplinked e-reserves. This paper outlines reasons why libraries should use DOIs whenever possible in the construction of deeplinked e-reserves and provides examples of how such linking can take place, including means for providing security and authentication. Other innovative uses for DOIs in academic libraries are suggested.
