These four supplements, which update a 1977 publication and a 1978 supplement, explain changes and additions in the priorities and administration of library programs, services, and activities funded under the Library Services and Construction Act (LSCA) in Massachusetts. Each of the four reports contains an introduction which reviews its purpose and background, the process for evaluation of staff activities of the Board of Library Commissioners, and the appointment and membership of the State Advisory Council on Libraries. Each document also outlines the purposes, criteria, and priorities of six programs for meeting state goals: a statewide and regional impact program, a local impact program, a statewide education and training program, a statewide public relations program, and programs for the blind and physically handicapped and the institutionalized. The 1979 supplement additionally provides a brief description of the 1978 Massachusetts Governor's Conference on Libraries and Information Services, an outline of a statewide standards program, and a 5-year graph for the overall state action program.
