I bought Steve Raichlen's (sp) book
"The Barbecue Bible." I was a little disappointed. Most of the book discussed recipes from Iran and Fiji and other places. Good info though, it's just pretty basic, you probably know all the tips he has for you.
My favorite book to read "North Carolina Barbecue, Flavored By Time", which has just a few recipes, some restaurant reviews, and a lengthy discourse on the history of NC Q. Good reading, makes me cook everytime I read it. Course, I'm North Carolina, so I'm prejudiced!
