This document summarizes a presentation about open textbooks and the BC Open Textbook Project. It defines open educational resources and open textbooks as instructional resources that are freely available online for anyone to use and adapt under an open license. The presentation discusses the high cost of traditional textbooks for students and its impact on enrollment and success. It then introduces the BC Open Textbook Project, which aims to create 40 open textbooks for the most enrolled subjects to increase access and affordability. The project involves reviewing existing open resources, adapting them for BC courses, and collaboratively creating new open textbooks. Case studies from other institutions that realized significant student savings by adopting open textbooks are also presented.
