This report provides readers with three primary products: significant data on statewide planning for cooperative computing, a process model to evaluate the development of cooperative computing in any state, and a structural model to evaluate the products of implementation in states that have implemented plans for cooperative computing. Such networks offer educators a vehicle both for providing computer services cost effectively and for increasing the level of service, as well as a mechanism for overcoming many of the barriers to interinstitutional resource sharing. A summary of participants in a national survey, and the characteristics of persons interviewed in case studies is included in the first appendix. The second outlines three case studies from the states of Minnesota, New Jersey, and Illinois. Each case study discusses planning, chronology, and strengths and weaknesses. A 31-item bibliography is also included. (Author/JEG)
