The parts of the book they give you are fine, but the publisher is greedy at the students expense. First off, the last five chapters are NOT included in the text! You have to go 'online' to get them. I bought a new copy with the access code, there is no longer any CD that comes with it, it is all 'online'. I use quotes b/c 'online' means registering your info with the publisher and then being allowed to get the material. I did this and had to carefully avoid checking all the right boxes to avoid spamming, which still didn't stop it. But after all that is done, they send you a confirmation email, an email I didn't get. Gmail might rightfully trash this companies emails. The result is denial of trying to register a second time with the same code, and nullification of that code if you don't authenticate within a week. So now I don't have access to any of the material and have to pay for the price of the book again to get a new access code. My other choice is to fail the quizzes!
If you are a student, don't buy this book for reference, as it is incomplete, and the website will probably only function until the next edition comes out. You can't buy it used as you have to pay for the access anyway.
Professors who are interested, please do your students a favor and stay away from this book. If you like the way it works, look into using the sixth edition, as I am pretty sure it has every chapter in it even if it is slightly outdated and it is still sold on Amazon. Your students can also buy a used copy. Even if they buy a new copy, they don't risk being sucked dry from this greedy publisher.
