I will second the votes for Ray Lampe, Mike Mills, Paul Kirk, and Steven Raichlens books...I have them all. I also recommend Barbeque and Sausage Making Secrets by Charlie Knote. The Great American Barbeque and Grilling Manual by Smoky Hale. Backyard BBQ by Richard McPeake. I dont think you can ever have to much information. Having said that, I am sort of getting away from "recipe type" books. The book I have read and enjoyed the most is Smokestack Lightning by Lolis Eric Elie. Doug Worgul's A Grand Barbeque is also a great read.
