We are two college mathematics professors who grew weary of forcing our students to purchase expensive college algebra textbooks whose mathematical content has slowly degraded over the years.  Our solution?  Write our own.  The twist? We made our college algebra book free and we distribute it as a .pdf file under the Creative Commons License.  What’s more, the LaTeX source code is also available under the same license.  Check the Downloads page for more information.  You can keep up with the latest developments at to our book at our blog, http://stitzy.blogspot.com/
