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 5 Rs of OER 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

To find material from off-campus, consider the following: 

  • Creative Commons: Includes images, a tool that allows openly licensed and public domain works to be discovered and used by everyone. 
  • Directory of Open Access Books: Aims to increase the discoverability of Open Access books
  • 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.
  • Your local public library, such as NYPL for New York City Residents
  • OER MetaFinder: Conduct a search for Open Educational Resources across 21 different sources
  • Wikimedia Commons: Wikimedia Commons is a media file repository making available public domain and freely licensed educational media content (images, sound and video clips) to everyone, in their own language. It acts as a common repository for the various projects of the Wikimedia Foundation, but you do not need to belong to one of those projects to use media hosted here. The repository is created and maintained not by paid archivists, but by volunteers. 
  • WorldCat: Contains over 48 million records, covering all materials cataloged by OCLC member libraries around the world
