Query: Outdated & not all that useful

I'm sure this book was tremendously useful when it was published in the mid-90's, but a lot has happened since then. Not only has brewing technology changed and advanced, but the internet means that all the information contained in this book (and more) can be found elsewhere. Even without the internet, your local home-brew shop will have equipment that surpasses everything detailed in this book. Don't bother with this book!
