Query: Warmed over info readily available elsewhere

I bought this book hoping that it would add something new to the information available on book collecting. As a collector of antiquarian tomes for three decades, I am always interested in looking at books of this nature.But this book disappoints. It's a mishmash of lists and information readily available elsewhere. The author is listening to some inner sense of direction which has little to do with the real book market or those who collect.To be honest, any book that gives a list of collectible books has limited value. Any such list or lists are based on a single author's opinions. The world of books is far too complicated for a single volume to fill any real need. The Ahern volumes come closest.If you are interesting in finding collectible books, you'd be far better off with the Ahern or McBride guides. In thened, this book will only disappoint.
