Research MBA Programs

Hi all,
I am planning to apply to business school next year for fall 2012 and I wanted to get some books that provided information on business schools (descriptions, class profile, tips, etc.) I know princeton review has a book- the best 300 business schools for 2011, but I was wondering if there were any others I should look into? Also does anyone know when princeton review will come out with the 2012 book?

Thanks
