I recently learned that the free digital textbook competition in California was completed and judged (http://news.slashdot.org/story/09/08/13/1450220/Open-Textbooks-Win-Over-Publishers-In-CA). The findings? Of the 16 books submitted, only 4 met 100% of the California standards. However, none of the "traditional" textbook publishers' books made the cut. Which did? Three were from CK-12 and one from H. Jerome Keisler.

If you're not familiar with CK-12, I'd recommend you check out their site: http://about.ck12.org/. They are a non-profit organization with a mission to reduce the cost of textbook materials for the K-12 market both in the U.S. and worldwide. Their books (currently Chemistry, Calculus, Trigonometry, Geometry, Biology, Life Science and Earth Science) are released under a Creative Commons Attribution-Share Alike license.

It is exciting to see such progress in the realm of accessible, open information. Bravo, CK-12, and a big "thank you" to California for pushing America toward a brighter tomorrow.
