Poster presented at ALA Annual Conference 2013, Chicago, IL / As the University of Arizona Libraries employ a 21st century user-centered approach to information resource management, we have adopted a Patron-Driven Acquisitions program. Fundamentally, the program is based on the model of users as the drivers of library acquisitions. By embedding order records in the library catalog and by identifying user needs through interlibrary loan requests, the library is able to acquire targeted information resources that more efficiently meet the research needs of our users. This service significantly enhances the user experience and allows the UA Libraries to see greater use of our resources.
