Open Resources

Open Educational Resources, or "OER" are defined as "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".

The 5R activities are:

  1. Retain – make, own, and control a copy of the resource
  2. Reuse – use your original, revised, or remixed copy of the resource publicly
  3. Revise – edit, adapt, and modify your copy of the resource
  4. Remix – combine your original or revised copy of the resource with other existing material to create something new
  5. Redistribute – share copies of your original, revised, or remixed copy of the resource with others

OER textbooks are not necessarily in the public domain, but are freely available to download and use following the Creative Commons Licensing (usually just cite!) 

Most of the time their license allows educators to share and remix content, but check each text individually to be sure.
