**Elementary Algebra**textbook found on the FlatWorld Knowledge website. You will find that the content is fairly modular, I have written it from the ground up with the expectation that instructors will modify it to suit their particular course. I am confident that everything needed for a Beginning Algebra (Algebra 1) course is covered, but feel free to MIYO (make it your own) by customizing it as you please. This textbook has the advantage over other open source material in that it has been thoroughly reviewed and vetted through the traditional publishing process. (Note: Be patient with the website, there are many math elements to be rendered for the web.)
