This directory lists more than 900 organizations that provide individuals with access to the ERIC database and related resources. In order to help users quickly locate organizations where ERIC resources and related services are available within a geographically short distance, the service providers are presented in three sections covering the United States, outlying territories, and foreign countries. The directory updates the 1986 edition and includes new information service providers as well as 1989 data for previously listed organizations. It is derived from an online database that is updated on a continuous basis and will eventually be available for public access. Entries have been expanded to include hours and charges for special services. Organizations are included that: (1) provide computerized searches of the ERIC database on a regular basis, irrespective of whether the service is available only to a restricted community (e.g., state education agency or university faculty only) or to all users; (2) are current ERIC subscribers and maintain sizeable microfiche collections, or are former subscribers whose collections cover a 2-year or longer period; and (3) subscribe to and collect ERIC publications, including "Resources in Education,""Current Index to Journals in Education," the "Thesaurus of ERIC Descriptors," and/or ERIC Clearinghouse documents. Also provided are a sample directory entry, statistical tables showing the geographic distribution of information service providers and the types of organization they represent, an alphabetical index of information service providers, and a directory of the ERIC system components.
