Query: A Self-Published Book

I'm a big believer that skin care and looking good take some effort. I consider myself pretty widely-read in the field of health and beauty, so I was interested to read this book, "Total Rejuvenation: From Skincare to Scalpel". It seems to be self-published, by one of those printers you pay to print whatever you write. I didn't know that Amazon stocks self-published books. This book reads more like an extended brochure. I guess it would be useful if you're already one of Dr. Cohen's patients or planning to become one. The title of this book is cute, but there's much better information and good quality writing out there in real books that have been selected for publication by real publishing houses.
