Our startup is working to fix the mainstream textbook problem. Specifically, I think the biggest ripoffs are the textbooks for first-year students; they're totally full of bullshit, so our mission is to replace them with more concise, and more affordable books.<p>So far we have two titles: one on precalc+mech+calc (3 in 1 for the win), and a second on linear algebra (see my profile for links). We're currently looking for authors to write the <i>No bullshit guide to biology</i>, and <i>No bullshit guide to chemistry</i>. If you have teaching or tutoring experience with these subjects, please get in touch.<p>Between the excellent OER books that available, and independent publishers like us, I think we can fix the textbook cartels. I give them 2-3 more years, then they're history.
