According to Creative Commons, OER or Open Educational Resources "are teaching, learning, and research materials that are either (a) in the public domain or (b) licensed in a manner that provides everyone with free and perpetual permission to engage in the 5R activities:
Open educational Resources are low or no cost to students, and also give faculty the ability to customize their course content to match exactly what they need.
"The Mason OER Metafinder helps you find Open Educational Resources. Unlike other OER discovery sites (e.g, OER Commons, OASIS, MERLOT, OpenStax, etc.) 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 22 different sources of open educational materials as you hit the Search button."
