The Brewers Association's Guide to Starting Your Own Brewery is, as other reviewers mention, a collection of articles and not so much a manual.
A person who is serious about starting a brewery will need to buy more books and learn a lot more after reading this book, but it's a good start for an outsider. Anyone who ever worked in a brewery before, or has experience running (not working in, but running) a restaurant, you could probably skip most this book and move on to more detail oriented books.
However, there is a lot of very good information in this book, and it has a lot of uses. This is a great place to start for anyone considering opening a brewery or brewpub, but has no experience in either industry. This isn't about brewing beer, it's about the industry and some of the logistical headaches associated with a brewery.
Chapters include topics like choosing the right flooring for the brewery, waste water, TTB regulations and more. If nothing else, you should buy this book only to learn about all of the things that you haven't considered when you think about opening a brewery. The Brewers Association's Guide to Starting Your Own Brewery also provides a few good numbers and spreadsheets to give you some idea of how the money goes.
