Participation by agencies in a network can provide access to a wider range of services and resources for the handicapped and can enable additional agencies to take advantage of information regarding specialized resources and services to the benefit of unlimited others. The major obstacle to effective networking is the fear that participation in a formal network will erode an agency's control over its own data. A successful network involves careful planning, understanding financial requirements, establishing effective interagency cooperation and communication, and utilizing computer technology as a networking tool. The most important purposes of networking are communication and cooperation, establishment and delivery of service, and creation of a comprehensive quality data base. (SBH)
