Query: Great book with one huge flaw!

As others have said, this book is extremely extensive. It covers just about every notational circumstance (available up to the mid sixties that is) in great detail. This is my number one reccommendation for a notation book.However, the section on Jazz is absolutely horrible, and offensive. Not only does it contain numerous flaws, it is missing a ton of stuff that the Jazz composer needs to notate. Also, it is offensive in that he refers to most Jazz music as "not serious." The book would be almost perfect if they would just leave the Jazz section out altogether. He apparently did not take very much time researching Jazz compositions (I don't think he every looked at one!) and did not put an importance on that chapter.
