Ken,
I'm in the USA and I'd purchase one to if it goes on CD, and I think many in the States would be thrilled to buy one. Let me know if you get it done and I'd be happy to help you sell them over here if you need any help.
I'll put my name down for one and I'm sure the Hred Registrars in each of the countries that breed Dexters, would all like to have a copy. It would pay to email the Dexter Societies and take orders.
Would it be possible to scan into the computer all the pages? Or does the information have to be entered by hand? What a long process. :p
