dog training books best

What are some books on dog training more effective to use? Which is better?
I try to buy a good book dog training so you can train my dog at home. There are so many things I do not know it would be best to get. So if you've used a pound of dog training, let me know what you think.
Two must read books for dog problem: Soft modern by David Weston and the other end of the leash by Patricia McConnell. Once I asked this question on a forum and has some good answers here's the link if you want to output: ETA http://www.dogforums.com/2-general-dog-forum/35912-need-your-guy- contents.html: I would stay out of the book I just read Koehler Training and appauling. In general, stay away from books that focus on the negative training.
