Earlier this year, the Ontario government made a big commitment to open textbooks, investing millions of dollars to create new open texts in fields such as history, finance, politics, the environment, engineering, and the sciences. The resulting open textbook library at ECampusOntario now features hundreds of texts that are free to use for everyone. The Ontario initiative follows leadership in the OER field from BC Campus and its open textbook project. The BC effort has saved students millions of dollars with adoptions by dozens of institutions putting them into use in hundreds of faculties for over 1600 courses.
