How do PDA programs supplement, enhance, or replace traditional collection development models? What have libraries learned from implementing PDA programs? Doug Way joins us for a presentation and discussion of e-book PDA in academic libraries. He will also discuss what Grand Valley State University has learned since implementing a PDA program in 2009.
