Open Education Resources (OER): Finding OER

An OER guide for CDU staff and students

Where to start your search for OER

For an initial search of any OER content, we recommend you start with Mason OER Metafinder (MOM) which has broad, real-time search capabilities. It will enable simultaneous searches across 21 different sources of open educational materials, including well-known OER repositories such as OER Commons, MERLOT, and OpenStax, and also sites such as HathiTrust, DPLA, Internet Archive and NYPL Digital Collections.

For an initial search of OER textbooks, we recommend starting with the top five major textbook platforms: MERLOT, Open Textbook Library, OpenStax, OASIS, and BC Open Textbook Project.

Finding OER


The website Creative Commons Search offers a convenient way to search for content provided by independent organisations. You can limit to the type of resource you are searching for example YouTube or Google Images. Be aware that the results displayed may not always be under a CC license. You should always verify the CC license before using the content.
