Abstract: An annotated listing of educational information sources is presented for educational professionals and policy makers. Sources include: printed and computer-access tools; private organizations and government agencies that provide direct assistance or referral services; commercial bibliographic services; and state library services. Some services that access foreign or international data are included. Following a brief discussion of background principles, the material is presented under 3 major categories: printed research tools (e.g., dictionaries, directories, bibliographies, abstracting and indexing services, statistical sources); special subjects (special education, instructional materials guides, printed sources on finance and government); and nonprint sources (e.g, computerized retrieval sources; educational, and financial information nonprint sources; institutional instruction materials information sources; and state library services for educators). A brief final section identifies writing guides and style manuals for administrators, researchers, teachers, and dissemination specialists. (wz).
