ERIC is a database sponsored by the U.S. Department of Education that contains education-related journal articles and documents. It was established in 1966. ERIC documents include papers from conferences, reports from school districts and state education agencies, and doctoral dissertations. Searches can be limited to peer-reviewed journal articles or full text materials. Controlled vocabulary terms called descriptors help users find information, and a thesaurus provides scope notes and related terms. Boolean logic can be used to combine or limit search terms. Some full texts are available directly in ERIC, while others must be requested or accessed at a library.
