Rolling with PDA and DDA: How Academic Libraries Can Use Patron-Driven and Demand-Driven Acquisition Techniques to Build Library Collections With Minimal Management and Budget

Patron-driven and demand-driven acquisitions (PDA/DDA) have been utilized for some time in academic libraries, but some university libraries are still new to the process. With changes in the last couple of years regarding shortterm monograph loans becoming cost ineffective, the popularity of streaming video PDA, and library materials budgets increasingly being cut, the conundrum of successfully implementing a DDA/PDA program and how to evaluate its effectiveness is a question many libraries need to answer. In the fall of 2015, the College of Staten Island Library-CUNY, implemented a small DDA monograph pilot program with Yankee Book Peddler (YBP) and EBSCOhost e-books to build its collections in academic areas new at the college. The goal was to offer patrons immediate on-demand selections in areas that might need additional collection building in depth and breadth but will take some time to accomplish by collection development (CD) librarians. The implementation and the results of this DDA pilot project, as well as in the fall of 2016, a new streaming video PDA program with Kanopy Streaming, will be discussed.
