Over the past several years there has been a growing interest among academic libraries in patron-driven acquisitions (PDA). As part of a broader shift in its collection development philosophy an academic library decided to implement a large-scale PDA program, and in the fall of 2009 added to its catalog 50,000 MARC records for books it did not own. This session will examine the first year of this project. The rationale behind that decision, the financial and collection impact on the university, lessons learned, and the state of PDA at this university today and in the future will all be discussed.
