Sixteen free high school math and science textbooks were evaluated based on state standards. Almost all the books were Creative Commons-licensed works produced by individuals and nonprofits, with the exception of a consumable biology workbook from Pearson. Participants diverged wildly on open-source versus free-as-in-beer, DRM versus open formats, whether books ought to be fluid or guaranteed not to change for a set period, and on top-down versus bottom-up approaches. Computer manufacturers and traditional publishers were there in force to explain why they should get a bigger share of the shrinking California education budget."
