Query: Poorly organized, little content

This book is a very difficult book to use. No index, bad alphabetizing of lists, no cross referencing. It lists mostly high-end bottles, and ignores others. It has pages of useless content. e.g. bottle club listings, bottle dealers, etc - all things that are out of date a month after publication and best found other ways. That space could have been used for something useful, like an index. I recommend this to no one.
