Maybe this is a silly question, but how much information generally changes year to year? None of the 2011 guide books are for sale and I want one now, lol 
Would it be a waste of money or is most of the information the same?
I know any pricing included in the book will be different, but that isn't a big deal.
Thanks experts!!
