Open and Affordable Course Materials

This guide supports UMD instructors with using and creating open educational resources (OER), affordable course materials, and open pedagogical practices.

Find Existing Open Educational Resources

Every year, more high-quality open course materials are published in more subject areas. You can use these as-is, remix or customize them for your course (if their license permits), or simply browse them for inspiration.

The repositories below include a wide range of open textbooks and teaching materials. You can search most repositories by keyword or browse by subject. Many resources are listed across multiple sites, but others are harder to find. Search different keywords in multiple places, and make sure to double-check the terms before reusing anything!

It can be daunting to wade through OER repositories, and there are more than what's listed here. Please schedule a consultation with us if you'd like support finding relevant OER for your courses.
