Finding OERs

Due to high volumes of Open Educational Resources available online, it can be difficult to search for OERs if you do not know where to look.

You may want to start by searching the Mason OER Metafinder. The Mason OER Metafinder searches across prominent OER collections including MERLOT, OASIS, and OER Commons. While it is very comprehensive, it still does not search through every available OER.

Can't Find What You Need?

If you are having trouble finding resources, complete our Request to Locate Open and Affordable Educational Resources Form. We will be in contact with a list of resources that we could locate based on your needs. While new OERs are being created everyday, there is no guarantee that we will be able to find all the resources you need for your course(s) as they may not exist yet.
