This report describes a program to expand the Books by Mail program at the Monterey (California) County Library. An introductory section provides background information on the development of the program, and the second section discusses the process of identifying target populations, which include those in geographically remote areas and the Correctional Training Facility (CTF) in Soledad. Strategies for publicizing the service are described in the third section. Three aspects of the Books by Mail service are detailed in the next section: (1) the collection, which includes popular trade and mass paperbacks as well as bestsellers leased through Baker and Taylor; (2) the catalog--a selection tool for subscribers--and its components; and (3) library procedures for service delivery. The two final sections briefly describe other activities of the Books by Mail program such as the newsletter, summer reading programs, and school visits. The appendixes, which constitute the major part of the report, contain a manual for CTF requests, and a tutorial for the Books by Mail program management system, which uses the PFS series of microcomputer software.
