Finding OER: Getting Started

Getting Started


Many OER resources have been created and are available on the web, including open textbooks, courses, multimedia resources, and data. These can be found by searching regular search engines (like Google), but it is much easier to find them through dedicated OER repositories or libraries. Below is a sampling of such repositories and libraries.

  • OpenStax Textbooks

  • The Open SUNY Textbooks
    Textbooks are available for anyone to access, download, and reuse under the terms of open licenses.
