Chapters in describe how a small town library defends the relevancy of its services at a town meeting, how a special library documents the value of its services to cost-conscious management, and how academic libraries can become involved in university- and college-level assessment programs. Librarians seeking to develop their own assessment methods will benefit from practical advice on assessing diversity in the library, and helpful suggestions for improving reference services through training workshops, peer-coaching, and changes in organizational climate.
