Free and affordable course materials for Oregon State University faculty

Adopt, adapt and author Open Educational Resources at Oregon State

By integrating OER into your course, you can reduce or eliminate course material costs for your students while retaining complete freedom to customize your course content. Oregon State faculty have access to thousands of free, openly licensed titles globally, alongside a growing repository of open textbooks authored right here at OSU.

Defining high-quality OER

To help evaluate these materials, Oregon State led the development of A Guide to Open Textbook Essential and Exemplary Features in collaboration with the Open Education Network. This comprehensive resource can be used to evaluate, adapt or create high-quality open textbooks.

Frequently asked questions about OER

Fundamentals and quality

OER are free, openly licensed materials — such as textbooks, full courses, modules and assignments — that expand access to knowledge. They grant all students day-one access to learning materials, drastically reducing education costs and empowering faculty to freely adapt and customize content to fit their specific teaching needs.

Many open educational resources undergo a rigorous academic peer-review process identical to traditional commercial textbook publishers, though individual review standards vary. A high-quality open textbook will explicitly state its peer-review status, review type and the credentials of the reviewers.

The original author is responsible for updates. High-quality OER digital documentation includes a version control table at the end of the open textbook to log updates.

Instructional effectiveness of OER meets or exceeds traditional commercial materials. A decade of research shows that students perform as well, if not better, when using openly licensed materials.

Benefits and adoption rates

  • Day-one access: Eliminates learning delays for students waiting on financial aid or working extra hours to afford books.
  • Full adaptability: Faculty can legally modify content to match a 10-week OSU term or incorporate locally relevant material.
  • Student savings: Over 60% of students reported not purchasing at least one required textbook because of cost. Replacing a $100 textbook in a 45-student course section helps avoid a total of $4,500 of textbook costs in a single term.
  • Academic gains: OER use correlates with lower course drop rates, higher student engagement and predictable lesson planning.

Licensing, print and alternatives

OER content typically carries a Creative Commons (CC) license, which legally permits the public to share and modify the work under conditions set by the author. Because permissions vary by license type, contact Oregon State’s Open Educational Resources Unit for a consultation.

Not automatically. While free for students to access through university licensing, most of these materials carry "All Rights Reserved" copyrights and cannot be modified by faculty. However, university-licensed library resources remain excellent alternative tools for eliminating student out-of-pocket costs.

Most publishers of OER textbooks offer students the option to download the textbook in a PDF format and print it via a local copy shop.

Bound, low-cost print versions of major titles (like those available through OpenStax) can be bought on Amazon.
