Mason OER Metafinder (MOM)The Mason OER Metafinder allows you to simultaneously search across the multiple OER repositories (e.g., MERLOT II, OAOpen.org, OER Commons, OpenStax CNX, etc.) as well as many open archival repositories (e.g. HathiTrust, Internet Archive, Project Gutenberg, etc.).
Openly Available Sources Integrated Search (OASIS) is a search tool that aims to make the discovery of open content easier. OASIS currently searches open content from across different sources and is expanding daily. Great place to search when you know what type (audio, textbook, etc.) of material you are looking for.
