Open Educational Resources (OER)

This guide provides information about Open Education Resources (OER) including where to find them, how to use them, and how to create them.

Open Textbook Library

Open textbooks are textbooks that have been funded, published, and licensed to be freely used, adapted, and distributed. These books have been reviewed by faculty from a variety of colleges and universities to assess their quality. These books can be downloaded for no cost, or printed at low cost. All textbooks are either used at multiple higher education institutions; or affiliated with an institution, scholarly society, or professional organization. The library currently includes over 750 textbooks, with more being added all the time.

The Open Textbook Library is supported by the Center for Open Education and the Open Textbook Network.

Did you know that you can also use existing library resources in your courses? Instead of or in a supplement to textbooks or OER resources, you can add articles, multimedia, and ebooks that are available through the library to your syllabus.

You can search our UDC Search catalog or visit the A to Z Resource List to find material for your course.
