Assessing the strengths and weaknesses of a library collection is an essential component in the collection management process. Collection Assessment in Music Libraries is a compilation of papers that present an overview of current approaches to and concerns about collection assessment for music libraries. This report should be part of the working collection available to all music librarians and collection management officers. Edited and introduced by Jane Gottlieb, the book contains articles by Peggy Daub (The RLG Conspectus: Its History and Applications), Elizabeth Davis (Guidelines of Evaluating Music Collections as Part of a Regional Assessment Plan), Sherry Vellucci (Technology for Collection Evaluation: Amigos and Other Tools), and Lenore Coral (Evaluating the Conspectus Approach: Problems and Alternatives). An extensive bibliography is included. Understanding and utilization of the methodologies available to evaluate music collections will better insure that libraries fulfill their mission of meeting users' needs.
