How libraries add value -- Evaluation -- Evaluation techniques and methods -- Input measures -- Process measures -- Output measures -- Approaches to identifying outcomes or impacts -- Outcomes in special libraries -- A balanced scorecard -- Building a library balanced scorecard -- Communicating the value of a special library. "Describing how value is added and how it can best be measured, Joseph Matthews explains different types of evaluations (models, implications, and methods) and a variety of measures (input, process, and output). He shows how a cost-benefit analysis and a library balanced scorecard, along with effective communication, can position the library as a "value center" rather than a "cost center." A glossary, list of recommended reading, and an appendix (including a library benefits survey and a table of measures with respective definitions) make this the ultimate means of establishing the value of your library - an essential guide no special librarian should be without!"--Jacket.
