Librarians have historically relied on the perceived value or goodness of the public library as a means to garner financial support. Yet it is now becoming apparent that public libraries must demonstrate, using an acceptable methodology, the economic value of the library and its services. A compendium of valuable information about the research and literature surrounding this issue of demonstration, this book reviews the various approaches that have been used in assessing the public library's value.Matthews suggests methods for a library to develop better means of communicating with their funding decision-makers and other stakeholders. By analyzing input, process, and output measures, and combining these with measures of the economic and social benefits produced by the library, he offers a portfolio of approaches that enable today's librarian to both measure effectiveness and to communicate its value to its stakeholders-the communities it serves.
