Based largely on recommendations from a 1986 strategy study, this long range plan for the improvement of library services in Idaho addresses goals and activities for the years 1989-1991. It is intended to support the direction of library development begun in 1984 to improve services to the user and to meet Library Services and Construction Act (LSCA) priorities where they coincide with needs in Idaho. Section I describes the purpose and development of the plan, while Section II provides information on the administration of the plan, including its goals, policies and priorities, criteria and procedures, coordination of library programs, dissemination of LSCA information, and evaluation of the LSCA program. User and library needs are discussed in Section III, which covers the library public; unserved areas; public, academic, school, special, and institutional libraries; the State Library Agency; and the Library for the Blind and Physically Handicapped. The discussion of public libraries includes library users; special populations (illiterate, disadvantaged, limited English speaking, elderly, and handicapped); community information referral centers; and major urban resources libraries. Interlibrary cooperation is reported in Section IV under the headings of resource sharing, automation, and networks, and Section V presents the long-term plan. Goals and activities of the plan are presented under three headings: Title I, Public Library Services; Title II, Public Library Construction; and Title III, Interlibrary Cooperation and Resource Sharing. Appendixes contain the minimum eligibility requirements for participation in the LSCA grant program and an outline of Title II hearing procedures. (SD)
