ERIC (Education Resources Information Center) is sponsored by the U.S. Department of Education to provide extensive access to educational-related literature. ERIC provides coverage of journal articles, conferences, government documents, reports, bibliographies, directories, books and monographs.
Each ERIC record is assigned a unique accession number in the collection. These are also known as the ERIC Document Number (ED Number) and ERIC Journal Number (EJ Number).
EJ Numbers – Refer to articles published in education journals
ED Numbers – Refer to education documents such as teaching guides, research reports, bibliographies, issue papers, instructional materials, and test and evaluation instruments.
ED Numbers are classified as levels 1-3.
· Level 1 - Reproducible in paper and microfiche and since 1993 in electronic format; materials issued from January 1993 - July 2004 are available at no cost through http://www.eric.ed.gov
· Level 2 - Reproducible in microfiche; full-text is no longer available through ERIC, but records remain part of the database. Available through Hekman Library.
