I have a newspaper article here. The headline says that B.C. is to lead Canada in offering students free, open textbooks. It heralds the program there to work on open education resources. The date, interestingly, is October 16, 2012, so we see things that have changed over the last five years, in this case in the growth of open education resources.
We also know that at individual universities, this has saved students hundreds of thousands of dollars. Overall, in British Columbia, they're thinking $4 million or $5 million in the last few years of having free, open, accessible, online textbooks replacing costly versions from private publishers.
