Another site for free college text books!

OpenStax is a part of Rice University developing free books for K-12 and university application. The books are mostly geared towards 101-level coursework and don't cover a huge number of subjects, for example, only two computer science titles are listed. One is an Introduction to Python, I downloaded it (400 pages) and looked over the TOC and I approve of the structure of instruction. I'd like to see things covered more deeply, but for a 101 book, I think it's quite adequate. I'll take a look at the astronomy book next (1100 pages), it's been a good twenty years since I took an intro on that class.

Still, it's a beginning!

The books are free to download (PDF) or access online and can be used by instructors in classroom settings as long as proper copyright attribution is maintained.
