To meet information needs of teachers and administrators, the Nassau County Board of Cooperative Educational Services in New York State entered into an agreement with the Educational Services Group of Bibliographic Retrieval Services (BRS) which provides access to 30 national databases, and also created a "private" file or database comprised of information submitted by eight teacher centers in New York State. Using microcomputers, both intrastate access among teacher centers and intracounty access among seven school districts are possible. The "pay as you go" system has increased search services from between 65 and 75 to over 800 searches a year. A diagram of the information network, which has the School Practices Information File (SPIF) as a core, and a description of the development of the system are provided. Appended are a sample copy of a statement prepared by Bibliographic Retrieval Services detailing usage for 2 weeks in November and a sample billing for a school district's use of the online service.
