Open Educational Resources (OER)

Resources and information about OER, where to find them and how to use them.

What Are OER?

A Human Timeline of Open EducationOpen Educational Resources (OER) are educational materials, including textbooks, full courses, syllabi, lectures and lecture notes, coursework, and more, freely available on the internet either in the public domain or under specific licenses.


According to the Bureau of Labor Statistics, the average cost of a textbook has increased 125% since 2002. Many students pay for textbooks with student loans, thus increasing their debt load. The use of OER helps to defray costs for students.

Additionally, the ability to adapt the material gives professors more control over the materials they use in class, letting the textbook fit the course instead of the course fitting around the textbook.

OER have been put into use in schools large and small, public and private. Here you'll find collections of OER by type and source, as well as news about OER initiatives all over the U.S.

How Do OER Work?

OER materials are either in the public domain or have been licensed for reuse and, sometimes, remixing and redistribution. Publishers of open coursework, including textbooks, are generally supported by academic institutions and philanthropic foundations, and those who write them do so with the express purpose of making the materials freely available for use by other professors and students. This way, not only is the material available for anyone who needs it, but it's also easier to continually update and improve the information available within.
