These three collections of reports comprise the objectives, background information, project descriptions, and evaluations for public library programs funded through the Library Services and Construction Act (LSCA) in Massachusetts during the fiscal years 1977, 1978, and 1979. The projects reflect the efforts being made by librarians to provide services to unserved and underserverd segments of their population. Included are projects related to library services for children, young adults, the elderly, the institutionalized, the physically and mentally handicapped, and persons with limited English speaking ability, as well as community/library analysis, community health information, and other community projects. Some of these projects involve library cooperation. The 1977 document reviews 24 projects while the 1978 and 1979 documents review 28 and 24 projects respectively. It is noted that the 1979 projects were the first to be drastically affected by tax cutting legislation. (ESR)
