The ERIC collection
As stated on the About the ERIC collection page
ERIC provides unlimited access to more than 1.4 million bibliographic records of journal articles and other education-related materials, with hundreds of new records added multiple times per week.
AuthorClaim is licensed vendor of ERIC. But don’t worry, we are not selling anything, we just hold a licence that allows us to make the records available here.
We will update the ERIC collection once a year.
