This book describes techniques for evaluating services provided through library networks, including collection development, group purchases, and reference services. Providing guides for developing evaluation instruments, testing them and applying them, it is comprehensive in its treatment of evaluating network services. Featuring contributions from some of the leaders in the area of e-metrics (Oliver Pesh, Ebsco; Judith Hiott, Houston Public; Jeff Shim, ARL e-metrics; and Chuck McClure) this book is an integrated, updated knowledge base of events in this area since 1998. It also provides a great deal of experiential knowledge concerning what libraries should do, plan for, and use in e-metrics.
