I'm sure the topic has been covered elsewhere, but I purchased a copy of Palmer's "How to Brew" and so far it has been very informative. I know there is an older/simpler/free version online. I initially went there and, since it was helpful, decided to support the author by picking up the latest bound edition. I haven't had a chance to look at Papazian's book, "The Complete Joy of Home Brewing." Seems like he was one of the early pioneers and a lot of people recommend it. Although, I understand some of the information is not as up to date as it could be.
