Due to this thread I purchased the following books based on brothers recommendations:
John Willingham's World Champion Bar-B-q
The Kansas City Barbeque Society Cookbook: Barbeque...It's Not Just for Breakfast Anymore
Peace, Love, & Barbecue: Recipes, Secrets, Tall Tales, and Outright Lies from the Legends of Barbecue
Dr. BBQ's Big-Time Barbecue Cookbook: A Real Barbecue Champion Brings the Tasty Recipes and Juicy Stories of the Barbecue Circuit to Your Backyard
My favorite of the four was Peace, Love and BBQ. It spoke to me because I went to Southern Illinois University and was quite familiar with some of things Mike Mills was talking about in the book.
