On March 3 and March 4 2021, Leeward Community College co-hosted two one-hour sessions of “Become an Open Textbook Library Textbook Reviewer: A UHCC OER Workshop“. The other co-host was the Open Education Network. Participants were invited to submit a textbook review of one of the textbooks from the Open Textbook Library, for which they are to be paid $200 in overload, courtesy of University of Hawaiʻi Community Colleges. Kapiʻolani Community College supplied five reviews in History, Chemistry, Business Writing, World Geography, and Online Learning. The books were published by University of Georgia Press, OpenStax at Rice University, Arizona Western College, University of Minnesota Libraries and Kwantlen Polytechnic University Learning Centres. The reviews ranged from 4.5 to 5 stars out of a possible 5. These reviews are a contribution to educators worldwide looking for substantive open educational resources in their fields.
