The directory lists approximately 120 library information service programs in residential facilities for the mentally retarded. Each program is described in terms of its collection (journals, books, films, and tapes), space, services (story hours, reference questions, bibliographies, and translation services), budget, clientele, and program summary. Charts provide an overview of the individual programs, staff and resources in the residential facilities polled in 1970 as well as the audiovisual materials and equipment reported by the same institutions in 1971. A personnel directory lists librarians and audiovisual specialists by state and alphabetically. Programs are listed by state location. (GW)
