OERs (Open Educational Resources)

The OER Metafinder performs a simultaneous search across 19 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.
