This guide provides an overview of open educational resources (OER) and the impact OER adoption has on student success. It provides examples that focus on college affordability, perceptions of OER, and OER efficacy.

Introduction to Open Educational Resources

One popular type of OER is the open textbook. The Open Textbook Library contains over 900 open textbooks in a growing number of disciplines. Open textbooks are textbooks that have been funded, published, and licensed to be freely used, adapted, and distributed. The books included in the library 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. Read more about the library.

Open Textbooks

OpenStax provides free, peer-reviewed, openly licensed textbooks and accompanying ancillary materials, such as slides and test banks. OpenStax textbooks have been adopted at numerous universities throughout the world. In the 2017 - 2018 academic year, use of OpenStax textbooks saved $145 million for students at over 4,000 schools.


From Summer 2016 to Summer 2017, UTA’s Department of History saved nearly 4,000 students over $388,700 by using an open textbook in online sections of History 1311 and 1312.
