What is ERIC
It is the world's most extensive digital library of Education literature. Sponsored by the U.S. Department of Education, ERIC has been the premier source of education-related documents and journal articles for scholars, practitioners and students since its inception in 1966. 
                         ERIC’s reputation for comprehensive, in-depth and consistent, high-quality indexing of all types of education materials was built upon a “decentralised and relatively autonomous" network of 16 subject clearinghouses associated with colleges and universities across the country.
