The Mason OER Metafinder launches a real-time, simultaneous search across 22 different sources of open educational materials as you hit the Search button. 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. From George Mason University.
