The practice of collection development faces many challenges in the present and likely future library environment. The following text presents concepts for collaboration as viable solutions to these challenges for collection development in academic libraries. In particular, a model of collaboration involving department faculty representatives and library liaisons is discussed. Consulting professional literature on this topic has offered insight into the establishment of librarian-faculty relationships, the process of collaboration, benefits of collaboration, as well as problems that may result from such cooperative relationships. Examples are illustrated from experiences at three academic libraries: University of Nevada Las Vegas, University of South Florida, and Hillsborough Community College.
