I have all of Harry's books, even some of the memory and math books. I would be interested in anything new, even if it's a compilation of the older materail -- provided that Harry adds his comments, updates, etc.
However, my muchly-annotated copy of Close-Up Card Magic can never be replaced -- it has too many fond memories. The original ad for this book is one of the best magic ads of all time -- especially the line about if the pages were all rendered blank, the purchaser would still feel he had his money's worth.
Harry -- I think you were going to email me a pdf of CUCM at one point. My new email address is firstname.lastname@example.org
