Cheaper textbooks and better access for higher ed students with OpenStax https://opensource.com/article/18/6/openstax-open-textbook
@scottnesbitt Diversity is great, I just hope it won't fragment the community, and that the wheel isn't reinvented too often. It's great if we have four good introductory books on the same topic, but we're missing out if no efforts go into advanced material. And that's a risk if every new initiative starts from scratch.
Besides, I'm really wondering why wikibooks isn't used more.
