"Given that my book, United States Numismatic Literature Volume II, was quoted extensively by Mr. Buttrey, I possess some credentials to judge his work. I am flattered whenever my book is employed in shaping numismatic research -- that was the whole point in writing it. However, in researching his monograph, Mr. Buttrey used only one chapter of my book, whereas there were many chapters in Volume II (and Volume I) that would have pointed to relevant bibliography.

…it is clear that Mr. Buttrey's work is woefully incomplete. To have arrived at grave conclusions based on demonstrably superficial research does discredit to the author as well as to the publisher of his monograph."
