I doubt very seriously that you will get help with that question, as we have no copy of your book. You must put forth some sort of effort as to get help. Like maybe give a particular problem.
Holt, Rinehart, Winston, Littell & McDougal, pretty well know company but I still can't do anything without an ISBN or a copywrite date. Maybe you can log on to their website and get a bit further than here. http://my.hrw.com/
