An indepth study was made of each of the 16 libraries in the Association of South Central Oklahoma Governments (ASCOG) region. As an essential aid to library planning, census data was analyzed to determine the social, economic, educational characteristics, and the geographic distribution of the population to be served. The library survey looked at each library's facilities and services and how each compared to the minimum standards established by the Oklahoma Department of Libraries in its goals for 1975. The needs and special service characteristics of each library were also detailed. The study concluded that the major problem of libraries in the ASCOG region was lack of space for books and services. Finances were also difficult. Multicounty library systems were recommended as the solution. Specific suggestions were made for the development of such systems in each ASCOG county. (Author/SL)
