Open Educational Resources (OER): General OER Respositories

What is an OER Respository?
An OER repository is an aggregator of resources that can be searched and accessed from a centralized portal. Repositories contain FREE, open source, creative commons licensed, or public domain educational material. There are many OER repositories available, with new ones popping up all the time.

General OER Repositories

Below are several general OER repositories. See additional pages under OER Resources for textbooks, books and journals, courseware, and digital media.

  • Community College Consortium for OER

  • GoOpenNC
    Focus is NC K-12, but includes a variety of resources curated by NC educators.

  • Mason OER Metafinder

    The OER Metafinder performs a simultaneous search across 17 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. This tool was developed at George Mason University.

  • MERLOT

    The MERLOT system provides access to curated online learning and support materials and content creation tools, led by an international community of educators, learners and researchers.

  • OASIS

    OASIS (Openly Available Sources Integrated Search) offers users the ability to search a wide range of OER materials. OASIS also is the only tool that allows users to limit searches by creative commons licenses or by faculty review. This tool was developed by the Milne Library at SUNY Geneseo.

  • OER Commons

    From a single point of access in OER Commons, you can search, browse, and evaluate resources in OER Commons' growing collection of over 50,000 high-quality OER.
