Intended to serve as suggested guidelines for library and information services in state agencies, this manual was prepared for use by administrators, librarians, and other agency staff. The first section provides information for the agency director on state agency libraries and their administration, personnel, the librarian's role, facilities and location, budget, collection, services, accountability, reports, and interlibrary cooperation. This is followed by an outline of issues and concerns in library planning. Extensive information provided on the organization of the state agency library covers technical processes, acquisitions, selection of documents, the vertical file, collection classification, cataloging, and weeding the collection. Guidelines for administering the agency library cover materials loan and interlibrary loan, copyright law, users with vision problems or physical disabilities, and annual reports. Focusing on library use, the final section considers reference databases, publicity, library maintenance and procedures, and the importance of the agency library. Eight appendices include a list of local and state resources, Council of State Agency Libraries bylaws, a list and map of regions of cooperation, rules for filing catalog cards, information for ordering the United States Government Books Catalog, a table of frequently used measurements for library space planning, and a list of sources of equipment and supplies.
