Although many recent studies have been conducted on the implementation and results of patron-driven acquisition (PDA) initiatives at academic libraries, very few have focused on whether, or how, patrons’ selections vary from selection choices librarians would have made. This study compares titles selected by patrons during a PDA pilot program against titles chosen by subject librarians from the same PDA list. The findings may serve as a starting point for other researchers interested in the impact of user-oriented selection initiatives on a library’s collection development.
