The best book that I have seen is the Princeton Review Guide to Med Schools. It has a lot of great information regarding applications, interviews, and also has a profile for all U.S. and Canadian med schools, and DO schools as well. I bought the book a couple of years before I was going to apply and read through it a couple of times. I used it as a guide to decide which schools to research further b/c it gives info regarding the teaching styles, location, and other great info.
