The Mason OER Metafinder searches sixteen targets in real-time, instantly returning the top several hundred or so relevant hits from each site. Because it is a real-time search, it can take a bit longer than searches of pre-indexed content; however, as compensation, the results returned are absolutely up-to-the-minute for each search target. Additional results continue to trickle in as the search continues running and you begin examining your results. From https://publishing.gmu.edu/whos-using-the-mason-oer-metafinder/
