Descriptive information is provided on 22 networks sponsored by the National Institute of Education (NIE) or the United States Office of Education (USOE) for the dissemination of educational information. The directory is arranged alphabetically by network title, followed by its acronym, sponsoring bureau/office, major functions, network members, target audience, description, available publications, support contractors, date established, and central contact person. The appendices include a State Locator Chart showing which network components now function in each state and address lists for key participants in many of the networks. This directory and the two companion volumes listed as related documents provide reference tools for individuals and agencies involved in education dissemination activities. (Author/JPF)
