The bottom line

the long version

"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!"--BOOK JACKET.
