Comprehensive OER Search Engines
OASIS searches for open content from over 75 different sources. It is created and managed by SUNY Geneseo's Milne Library.
The Mason OER Metafinder helps you find Open Educational Resources. Unlike other OER discovery sites, with our Metafinder you aren’t searching a static database that we’ve built. Instead, the OER Metafinder launches a real-time, simultaneous search across 21 different sources of open educational materials as you hit the Search button.
Because it is a real-time, federated search, it can take a bit longer than searches of pre-indexed, curated content; however, as compensation the results returned are absolutely up-to-the-minute for each search target. Additional results will continue to trickle in as the search continues running and you begin examining your results.
A distinct feature of the Mason OER Metafinder is the scope of our discovery service. We’re searching 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.
This site is a collected, searchable database of all things OER. The collection is built from an initiative of the UNESCO/COL Chair in OER at Athabasca University and the UNESCO Chair in OER at the Open University of the Netherlands.
A global non-profit network promoting open education worldwide. This site houses links to OER textbooks, information about how to become involved in OER efforts, provides news and webinars for OER supporters.
