contents	Developing a Planning and Implementation Model for Bringing USEIN into Operation. O'Brien, Nancy Patricia Access to Computers Access to Information Educational Planning Educational Resources Electronic Text Information Dissemination Information Networks Information Sources Libraries Listservs Partnerships in Education Shared Resources and Services Users (Information) World Wide Web The mandates of the National Library of Education include a directive to become a principal center for information and services related to education. As part of this directive, a national network of education information, the United States Education Information Network (USEIN) has been proposed. This paper provides recommendations for developing and implementing a model for an effective education information network. Five key recommendations are presented from which other areas of activity and development can flow: the appointment of a provisional working group to develop bylaws and operating procedures for USEIN; the creation of a listserv to connect USEIN members; the development of a World Wide Web page devoted to USEIN with links to relevant resources and sites; the development of a master directory of education information and service providers; and the identification and solicitation of partners to participate in USEIN. Policies that will enable any of the network's users to utilize the network and its resources, regardless of technological skills or access to sophisticated computers, must be implemented and followed. Alternative mechanisms must be provided so that equal access is available to all. The philosophical commitment to provision of education information to all users, in all formats, through a variety of mechanisms, must be a transcending part of the process. (Contains 11 references.)
