Open Educational Resources (OER): Home

What are OER?

Open Educational Resources (OER) are teaching, learning, and research materials that are either (a) in the public domain or (b) licensed in a manner that provides everyone with free and perpetual permission to engage in the 5R activities for educational purposes: Retain, Reuse, Revise, Remix, and Redistribute.

Some free resources, such as Google Books or HathiTrust, may appear to be open. Because they require licensing or a paid subscription by the institution to access in full, they are considered paid resources.

The resources included in this guide are free to access and use, and vary from course material aggregators to specific textbooks. 

Digital Collections and Directories

  • Creative Commons: Includes images, a tool that allows openly licensed and public domain works to be discovered and used by everyone. 
  • HathiTrust: Works in the public domain in HathiTrust are open to all researchers, whoever and wherever they may be. Content in HathiTrust is discoverable through online search technologies within the repository and through Google, with no authentication, login, or password required. 
  • Directory of Open Access Books: Aims to increase the discoverability of Open Access books
  • OER MetaFinder: Conduct a search for Open Educational Resources across 21 different sources
