This directory providing an overview of current educational communication networks and activities was designed to improve educational information access and dissemination. It is a descriptive guide to some of the major private-sector resources in educational dissemination within seven general categories: education associations, professional membership organizations, educational laboratories and centers, advocacy groups, education-related organizations, multimedia organizations, and foundations. Information provided for each entry includes the name and address of the association or organization; its objectives, activities, and programs; membership; major sources of funding; organizational structure; and dissemination activities through publications, together with their frequency and intended audience. Each entry has also been assigned a referral number, arranged sequentially across categories, which is used as the reference code in the List of Organizations, Index, and Quick Reference to Activities. The Quick Reference to Activities provides both a glossary of organizations and a checklist of the specific activities and services they provide. The Index identifies organizations by subject area or special focus and by education level or target audience. (Author/JPF)
