Update on Free CK-12 Textbooks

Since I wrote the earlier post on these books, I've found that you can get ten of them free in the iBooks store (Chemistry and Life Sciences were missing when I checked) and download 9 of them as PDF files from the website. In the meantime, though, Amazon has added them as free books for those in the US. Make sure you have enough room, though, before downloading, as the total space required is significant. The color pictures and such look great on the iPad, though.
