The Appalachian Adult Education Center (AAEC) conducted a study of the services of two institutions, public libraries and public schools, serving disadvantaged adults in cooperation. The study was conducted at four AAEC centers in Alabama, South Carolina, Kentucky, and West Virginia. The problems explored included information needs of disadvantaged adults, and the organization personnel, programs, and materials in the two institutions. Methodology and recommendations were given for selecting sites and staffs, initiating coordination, developing model center guidelines and plans, choosing target groups, training staffs, monitoring demonstrations, and other aspects of the projects. The influence of the study on adult education and libraries, its failures, and its dissemination were evaluated. Activities of each of the four project sites in recruitment, materials, teachers, librarians, library cards, displays, student orientation to the library, delivery, community referral, possible continuation, and local contributions are summarized in chart form.
