The growing OER movement is developing textbooks, commentaries, question banks and other useful resources for education. Most of these resources are free to use, and many allow faculty to edit and redesign them to fit their particular needs. Below are some useful starting points for learning more about open educational resources and discovering ones for the courses you are teaching.

In addition, wikipedia is a free, openly licensed encyclopedia, and the digitization of legacy texts has made it easier to share materials now in the public domain.
