Case studies describing programs funded under the Library Research and Demonstration Component (II-B) of the Higher Education Act (HEA), and Title III of the Library Services and Construction Act (LSCA) are included. The awarding of grants, and contracts to support research and demonstrations for improving library and information sciences, education in information science and librarianship, and disseminating information derived from the program is authorized under the HEA II-B. Twelve projects responding to this program's emphases are described, including these four case studies: (1) a demonstration of how schools and public libraries reverse illiteracy; (2) interrelated library and basic education programs for disadvantaged adults; (3) the development of a computerized regional library system (OCLC); and (4) the development of strategies for dealing with information needs of urban residents. Title III of LSCA provides funds for support and expansion of statewide networks, local library cooperatives, and participation in multistate networks. Programs in Alaska, California, Minnesota, Mississippi, New Hampshire, New York, Rhode Island, Texas, and Virginia are included. Each describes state library development; management at the state level; impact of federal and state requirements and controls; use of funds; state membership in interstate and multistate networks; program strengths and weaknesses; future directions; and detailed descriptions of the projects.
