My son Brian spent a number of years working for the Scholarly Publishing Office of the University of Michigan Library and worked on many digitalization projects. 4 1/2 years ago on my 60th birthday (It seems like only yesterday) he sent me a reprint that the University of Michigan did of Prime's 1861 edition of Coins, Medals and Seals. I am probably a bit prejudiced but I think that the quality is very good (or in numismatic terms Extremely Fine). It's very helpful to be able to use a copy of a book as a "working" copy without having to worry about ruining a rare 150 year old book. He has since moved to the University of Kansas in Lawrence where he is doing similar work, and now I'm a lot closer to my grandchildren.
