The worst part of being a college student? Pricey learning materials... they make even Ramen noodles a fancy meal. This fall, students at California State University will be at least be able to make a step up to fast food. CSU has announced a three-year deal with Nature Publishing Group for low-cost, interactive, web-based textbooks with access options for disabled students. The first to be offered is an introductory biology text, fittingly titled Principles of Biology. Students on the L.A., Northridge, and Chico campuses will each have varying payment and licensing models, but 49 bucks gets anyone a full edition starting September 1st. Professors can edit the content, which includes 175 "interactive lessons," access to a database of research papers, and assessments for students. It can all be used on any device from a slate to a computer and even printed if you prefer scribing your notes with pen and paper or won't be near an internet connection. Details are dry about future books using the system, but it looks like a promising break for college students. Still, before you get ready to ditch your books and backpack for more money and less backaches, we'd suggest skimming the press release after the break.
