Mason OER Metafinder 


The Mason OER Metafinder (MOM) helps you find Open Educational Resources.  Unlike other OER discovery sites with MOM you aren’t searching a static database.  Instead, the OER Metafinder launches a real-time, simultaneous search across 21 different OER repositories like OpenStaxOER CommonsMERLOT , HathiTrustDPLAInternet Archive and NYPL Digital Collections - where valuable but often overlooked yet often “open” educational materials may be found.  Given the many “standards” of metadata in the OER universe, it can’t guarantee that every item retrieved is “Open” in the strictest interpretation of that term, so make it a practice to check the rights of any item you use.
