To better coordinate the work of the 16 ERIC Clearinghouses with that of other information service providers, the Office of Educational Research and Improvement (OERI) conducted a survey that defined and described the clients and services of 100 public and private education-related clearinghouses. For the purposes of this survey, a clearinghouse is defined as a place: (1) where organized databases are maintained and continuously updated; (2) which maintains an extensive set of resources in a specific education-relevant area; (3) where information from the databases is available to the general public; (4) where staff actively share information with their constituents (e.g., through newsletters); and (5) which describes itself as a clearinghouse, resource center, information center, or information service. This directory provides basic information about each of the clearinghouses surveyed. Each entry contains the following information: clearinghouse name; address; contact person; telephone number; federal funding information; legislative authority; involvement with larger projects; projects within the clearinghouse; government monitor name and telephone number; content focus; key users; types of information provided; coordination with other clearinghouses; database names; type of accessibility; number of items in database; responsive user services; total annual requests; dissemination activities; number on mailing list; technical assistance; and compatibility with ERIC (Educational Resources Information Center). Both an alphabetical list of clearinghouses (table of contents) and a subject index are provided. (SD)
