This book is set up just like a phone book, if you are old enough to remember phone books. Actually, I think they do still make them, but I just toss mine. Anyhow, the formatting was not good for Kindle, but that was not a problem, since this was an ARC from NG, I just used the NG app. the book is broken into sections so you can reference what you are looking for, rather then read front to back like a regular book. It is divided into calls by subject, calls by book title, and calls by author. There are also listings for book stores and other places that are book related. When you call if you use extension 1001 you can leave your own message. If you use an extension in the book you can hear a message that was left by someone. There is so much in this book and every time I scroll through it I find something I did not see the times before. If you like books, reading, and innovative ideas, give this book a try. I do not recommend the kindle version as I mentioned the formatting.
