Technical Services Quarterly declared that the third edition "must now be considered the essential textbook for collection development and management . the first place to go for reliable and informative advice." For the fourth edition expert instructor and librarian Johnson has revised and freshened this resource to ensure its timeliness and continued excellence. Each chapter offers complete coverage of one aspect of collection development and management, including numerous suggestions for further reading and narrative case studies exploring the issues. Thorough consideration is given to* traditional management topics such as organization of the collection, weeding, staffing, and policymaking;* cooperative collection development and management;* licenses, negotiation, contracts, maintaining productive relationships with vendors and publishers, and other important purchasing and budgeting topics;* important issues such as the ways that changes in information delivery and access technologies continue to reshape the discipline, the evolving needs and expectations of library users, and new roles for subject specialists, all illustrated using updated examples and data; and* marketing, liaison activities, and outreach.As a comprehensive introduction for LIS students, a primer for experienced librarians with new collection development and management responsibilities, and a handy reference resource for practitioners as they go about their day-to-day work, the value and usefulness of this book remain unequalled.
