If you plan to collect only the more modern US Mint proof sets, the Guide Book that you've already purchased is about as good as you're going to get â" it has the most information on these newer sets.
If, however, you plan to venture further back into earlier US proof coins and sets, I would suggest that you locate a copy of Walter Breen's Encyclopedia of US and Colonial Proof Coins. It is the standard reference work on these coins. You can review its contents online here: http://www.pcgs.com/books/breen-proofs/
