OASIS was created by the Milne Library at SUNY Geneseo with the goal of facilitating the search for open learning materials. OASIS contains more than 155,000+ records from 52 different sources that have been carefully selected in collaboration with SUNY OER Services. You can limit search results by license, type of resource, subject, source, and reviews.
The Mason OER Metafinder was developed at George Mason University and searches more than 20 OER collections. You can limit your search to OER-specific sites, such as OER Commons or BCcampus, or expand your search to include open content sites like American Memory and Project Gutenberg.
