Might be worth looking at the Indian textbooks mentioned in this post: http://reganmian.net/blog/2008/04/06/many-great-free-textbooks-from-india/. Not clear that they are open but worth investigating.

It appears that someone may have hijacked the Open Tex Project link under “links” at your site.

I have a free third-semester calculus book which I wrote for a class I taught last year. The title is Vector Calculus, and it is released under the GNU Free Documentation License. You can download the PDF at the project page for the book:

I would like to suggest a recently published book, which is intended as a textbook for graduate students in several fields, including Pharmacology. The book is titled Drug Acceptor Interactions and is written by Professor Niels Bindslev at Copenhagen University. The link to the full text published under a Creative Commons license is: www.co-action.net/books/bindslev. Thank you for developing this site!

The Open Slate Project is about using the open-source process to integrate computer technology into the K-12 classroom, with some help from college students. The Slate is the essential hardware piece. Student slates are linked by a wireless network and capable of accessing Chalk Dust, the educational software and courseware portion of the project. To help bootstrap the Chalk Dust courseware we have set up a wiki and will begin working with K-12 homeschoolers this Fall.
Please add the Open Slate Project to your links page.

I suggest listing my Java programming textbook, which is
published under a Creative Commons license. It’s available in
an on-line version at http://math.hws.edu/javanotes/ and as a
PDF through a link at the bottom of that page. There is also
an open textbook on theoretical computer science, available
as PDF only, at http://math.hws.edu/FoundationsOfComputation/
