The National Commission on Libraries and Information Science held a Mountain Plains Regional Hearing in Denver, Colorado, on September 18, 1974. The Commission was particularly interested in the present status of library and information services in the region including: cooperative efforts, state interest in a national program, the use of new technology, continuing education programs, and service to American Indians on reservations. Witnesses gave testimony about university, state, public, medical, school, and Indian reservation libraries, as well as library education programs, networks, systems, cable television, and the Western Interstate Commission for Higher Education programs for continuing education. The witnesses came from South Dakota, Utah, Nebraska, Nevada, Wyoming, Colorado, North Dakota, and Kansas. The written statements of the scheduled witnesses are presented, including three reports from attitude surveys completed by the Colorado State Library. (LS)
