Open Textbooks are educational content distributed free with a few restrictions: typically, the material cannot be sold for profit and the authors must be credited. There is increasingly more and more academically sound course content available free on the Web. With the price of textbooks increasingly astronomically, it can't hurt to look at some less expensive alternatives. Here is a list of some sources that you might find useful for your classes:
