Library networks are much more than telephones, teletypewriters or closed circuit television. Networks are a new concept in library service that requires a new mentality on the part of every participating librarian in every type of library. Librarians wishing to join the growing information and materials community with its improving delivery system must be willing to accept the challenge of community demands. In Kentucky the network activity is planned around the "Kentucky Library Communications Network." This network is in the early developmental stages and although the machinery has been established, the essential "community" concept is some distance away. This manual is designed to help develop this"community" concept. From a description of the network relationship it goes on to outline procedures for use of the network by local public libraries, the regional headquarters library and department libraries. The appendices contain a sample form and instructions, acceptable abbreviations of selected sources for verification of interlibrary loan requests, and the National Interlibrary Loan Code, Annotated, 1968.
