Book excerpt: Evaluating Demand-Driven Acquisitions examines recent research in demand-driven acquisitions in an effort to develop an evaluation framework specific to demand-driven programs. The chapters in this volume focus on the criteria and methods that are used to evaluate the results of demand-driven programs in research. Case studies and pilot programs from all types of libraries—including interlibrary loan to purchase programs, catalog integrated strategies, and evidence-based collection development—help illuminate the current best practices and benchmarks for demand-driven evaluation. This book helps librarians and practitioners evaluate their existing demand-driven programs and make adjustments that could decrease costs or expand existing strategies. It is also suitable for librarians with new or emerging demand-driven programs to use as a framework for developing ongoing assessment programs or evaluating pilot programs. - Provides a comprehensive and up-to-date assessment of demand driven acquisitions research - Separates research findings by evaluation criteria for ease of use - Serves as a reference for diverse libraries, including academic, public, and corporate libraries - Synthesizes the most current research on this increasingly popular library strategy
