[ED-TECH] Free textbooks

There seems to be increasing interest in the use of free textbooks, both in Florida and nationwide. I know that James Nearing has "Mathematical Tools for Physics" available as a free pdf on the http://www.physics.miami.edu/~nearing/mathmethods/ web page.

Has anyone else at UM written a free textbook?

Is anyone at UM using a free textbook as the required text in your class?

Some sites with open source textbooks:

http://linear.ups.edu/opentexts.html - Go to the bottom of the page for articles about free textbooks, and lists of collections of free textbooks.
http://cnx.org/ - Connexions - Both modules and textbooks in many, many fields
http://globaltext.terry.uga.edu/ - The Global Text Project - Books in many fields

Finding an open source textbook may not be easy, since a salesperson doesn't come to your office, but the savings in cost to students can be dramatic and the ability to control the content can enhance your teaching.
