Patron-driven acquisitions (PDA), also referred to as demand-driven acquisitions (DDA), is a relatively recent development in the management of the book supply chain for academic libraries. In its simplest form, PDA is a just-in-time method, and an accompanying set of operational procedures, for acquiring library materials based on direct or indirect patron input. PDA has significant implications for the economics of publishers. This report surveys the marketplace for university press titles, identifies the share of books being sold to academic libraries, establishes a framework to analyze the impact PDA on university presses, and recommends strategies that scholarly publishers can adopt to address this transformation in one of the industry’s most significant markets.The Andrew W.
