Query: Boston's Gun Bible is a good buy

This is a great book. It's just chock full of great information. I read some every evening, and with pencil in hand. Other reviewers have already provided a lot of details - let me just say that you'll get your money's worth and then some in the first few chapters. Need a strategy for what to buy? It's here. Need a plan for when to shoot and how much? It's here. Want details on good gun buys for hunting and defense? That's here too. And I'm only 1/4 of the way through it all. The only thing I didn't understand is how it could be updated for 2009 when the publication date on the flyleaf is 2002.
