A survey instrument was designed and administered to obtain a broad base of information concerning the presence of computers and computer literacy classes in public libraries in Ohio, Indiana, Illinois, and Minnesota. The results indicate that 50.8% of the 100 libraries that responded to the survey (80.6% of the original random sample) have public access microcomputers while only 9.8% offer computer literacy training. Ohio leads in both the number of public access computers and in the number of computer literacy training classes. The scope of the literacy classes varies widely. Classes are frequently taught by staff members. Software is usually selected by the director or assistant director. Patron recommendation is the primary consideration in software selection. Most of the software used by children is educational, whereas word processing, resume preparation, and Print Shop type programs are typically employed by adults. Funding comes primarily from the libraries' line item budgets, but other sources, in order of their frequency, include individual donations, LSCA (Library Services and Construction Act) grants, Friends of the Library, and foundations. The cover letter and questionnaire are appended. (Contains 102 references.) (Author/ALF)
