“Open Educational Resources (OER) are teaching, learning, and research resources released under an open license that permits their free use and repurposing by others. OER can be full courses, course materials, lesson plans, open textbooks, learning objects, videos, games, tests, software, or any other tool, material, or technique that supports access to knowledge.” — SPARC (Scholarly Publishing and Academic Resources Coalition)

Consider using OER to:

  • Reduce textbook costs for students.
  • Increase access to course materials (e.g., available on-demand across devices).
  • Build collaboration (between educators, between students and educators).
  • Improve flexibility and material quality (e.g., tailored material for specific purposes, adding current content).

OER reduce barriers to education while increasing the quality of teaching and learning.

Where to Find OER Textbooks

  • In online textbook collections. OpenStax has free learning modules and textbooks both developed and peer-reviewed by educators. Open Textbook Library is another collection that pulls titles from multiple OER sources.
  • By discipline. OER textbooks serve many fields, including commonly required coursework and high-enrollment classes. The PSU Library curates materials by discipline.
  • By PSU faculty. PSU has its own publishing initiative, PDXOpen, which supports faculty in developing open-access textbooks.
  • Using search engines. Two great options to begin your search are OASIS and Mason OER Metafinder (MOM), which search across OER repositories and thousands of entries. These are particularly helpful for more advanced or specialized courses.
