The Mason OER Metafinder helps you find Open Educational Resources - this a great first-stop in your search across the universe of OER content.
MOM performs a simultaneous search across 17 different sources of open educational materials. 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.
MOM searches 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.
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 63 different sources and contains 160,535 records.
The Open Course Library (OCL) is a collection of shareable course materials, including syllabi, course activities, readings, and assessments designed by teams of college faculty, instructional designers, librarians, and other experts. Some materials (also called open educational resources, or OER) are paired with low-cost textbooks ($30 or less).
Many of the courses can be taught at no cost to students. Unless otherwise noted, all materials are shared under a Creative Commons (CC BY) license. OCL courses and materials have undergone testing for accessibility and have been designed using the industry-standard Quality Matters (QM) rubric for assessing the quality of online courses.
