Thesaurus of ERIC Descriptors. Comp. by the Educational Resources Information Center, Bureau of Research

The Thesaurus of ERIC Descriptors was developed by the United States Office of Education as a foundational tool for the Educational Resources Information Center (ERIC) network. Initially conceived in the 1960s, the publication was designed to provide a standardized, controlled vocabulary for the indexing and retrieval of educational research documents. By establishing a shared language for researchers, librarians, and educators, the thesaurus ensured that the vast body of literature collected in the ERIC database remained searchable and organized during an era when information management was transitioning toward early digital systems.

The design of the thesaurus focused on structural hierarchy and semantic relationships, utilizing a system of descriptors, related terms, and scope notes to guide users through complex educational nomenclature. It was compiled by professional information scientists tasked with maintaining the integrity of the ERIC database. While the work is largely utilitarian, it is regarded by information science historians as a milestone in the development of taxonomy and information retrieval, serving as a vital reference point for the academic community throughout the late 20th century.
