We originally featured the Mason OER Metafinder in the Scout Report on 5-18-2018, and it continues to be an outstanding way to find open teaching and learning resources.
The Mason OER Metafinder from The Mason Publishing Group at George Mason University Libraries is a powerful search tool that allows users to search record metadata from seventeen digital libraries and repositories, including the Digital Public Library of America, OER Commons, and AMSER-Applied Math and Science Education Repository. Searches are conducted in real-time and are not pre-indexed. To get to the actual metafinder, visitors should click on Mason OER Metafinder from the homepage. The metafinder allows users to enter search terms in full record (allowing users to search across the entire content of a document), title, author, or date range. Users can also choose which sources the metafinder should search by unselecting repositories below the search bars (all repositories are included by default). As an example, by searching for San Francisco in the full record search bar, the top 755 results are displayed from over a million sources retrieved. The option to narrow down results is available on the left-hand side of the search results. The Mason Publishing Group also offers a companion Sciences Metafinder, also available from their homepage, which specifically searches scientific repositories for science resources.
