The Mason OER Metafinder searches seventeen targets in real-time, including well-known OER repositories like OpenStax, OER Commons, MERLOT but also sites like HathiTrust, DPLA, Internet Archive and NYPL Digital Collections where valuable but often overlooked open educational materials may be found.

OASIS is a meta search tool developed by SUNY Geneseo that searches across 52 different OER sources and includes a range of materials, including textbooks, courses and corresponding materials, interactive simulations, public domain books, audiobooks, modules, open access books, videos and podcasts on a variety of topics — from anthropology to zoology. OASIS also is the only tool that allows users to limit searches by creative commons licenses or by faculty review
