Kristin's tips for finding OER or free teaching resources

  1. Talk with your colleagues to see if they are teaching with open or free resources.
  2. Find out what others are using for the same or similar course.
  3. Check OpenOregon, the HCC Course Repository (coming soon to HCC's Zero Textbook Cost site), or another large archive that lists materials by course. See above for Best Bets.
  4. Visit OpenStax, Open Textbook Library, or another open textbooks repository.
  5. Contact your campus librarian.
