This survey of Arizona library services includes an examination of the current library situation in the state, a forecast of future needs and the resources required to meet them, and a comprehensive plan for statewide library services. Procedures for the study involved questionnaires sent to all types of libraries in the state and each school district with a district library consultant or coordinator, visits to 32 libraries, two advisory committees, and a seminar attended by the advisory committees, the survey and state library staffs, and special library consultants. It was found that Arizona libraries are unable to meet the requirements of a rapidly increasing population. Recommendations for a cooperative, statewide system of library services, with the State Department of Library and Archives as the focal point, cover: state level services, district reference and service centers, district sub-centers, a statewide advisory council, strengthening the state library agency, defining roles and improving all types of libraries, needed legislation, recruitment and library education, library standards, and a program for public information. Appendixes include names of advisory committee members, the questionnaires and materials check lists used in the survey, and a 51 item bibliography. (JB)
