If you look hard enought you can find something bad about anything, look a little harder and you can find something good on any subject. Now for the person that has not found out what the book in good for.... send him to the out house so, he can reread it and maybe find a very good use for it out there, or keep the book in the house and use it in seeing a lot of chips that Iam sure are not in his collection. A book is just a guide and I would hope it would guide that collector into being a better collector. Just my two cents worth.
