Query: A let down

I was disappointed in this book, it remind of the old "5000 Guitar Grips" books with lots of raw info, but nothing on usage. I think there is a lot of info buried in the book, but there really isn't any examples to help the reader understand how to apply. I think if the author would take book and add some examples showing application the book would be great, but without it it's going to collect dust for most.
