This book contains a lot of good info, which I've found to be both interesting and useful as I get back into brewing after a break of a few years. I have Papazian also, and of the two books, I pick this one up more often, and find what I'm looking for more easily.
Despite the comments of some other reviewers, one doesn't need to be an all-grain brewer to find this book useful. I'm creating my own recipes using extracts and specialty grains, and find this book to be very helpful.
However, Miller is pretty repetitive. It is only a slight exaggeration that there are 3 chapters on each topic: on each on theory, equipment and method. I find that there is a moderate degree of repetition of material across these chapters. A consolidation of each topic into 1 chapter could well result in a 1/3 reduction in pages for the book.
I'll echo another reviewer, who commented negatively on the recipes towards the back. They are really just lists of ingredients, without discussion on method (eg. mash temperatures) or variables.
Having made these mild complaints, I'll go on picking this book up every day or so as I think about what to do for my next brew.
