According to a BC Ministry of Advanced Education news release, BC’s Open Textbook Project “already has helped almost 300 post-secondary students, who saved an average of $146 each on their textbook costs for the fall 2013 semester.” In the first phase of the project, 15 existing open textbooks were peer-reviewed by BC faculty and made available for free download in September 2013. Individual instructors at Capilano University, Douglas College, the Justice Institute of British Columbia, Kwantlen Polytechnic University, Langara College, and Northwest Community College used open textbooks in the Fall 2013 semester, bringing collective savings of over $43,000 to students.
