Open Textbook & OER Repositories

Concordia Library has created a list of open access textbook and open educational resource repositories for those who are interested in incorporating open sources into their courses. Open textbooks and OERs are openly licensed and freely available educational materials that can be used and/or adapted with few or no restrictions.

If you have copyright questions or concerns about using OERs, please contact Lynette Toews-Neufeldt

This toolkit will provide you with some considerations before you start using OERs in your classroom, in addition to strategies, practices, and web resources.
