Digital technology may not render obsolete one of the most famous admonitions about collecting, to buy the book before the coin, but it could modify it.
Dozens upon dozens of hobby-related books and other publications are available, for free, through Google Books, the Internet search engine's digitization program.
The efforts of the program, though vexation to some academics and copyright holders, have been very fruitful, especially for numismatic research.
Some of the latest names in numismatic research give the program positive reviews.
Among these are Roger W. Burdette, R.W. Julian, Joel Orosz, Leonard Augsburger and David W. Perkins.
The latter three are also on the board of the Numismatic Bibliomania Society, a group of people that collect and advocate for numismatic books and periodicals - at least printed versions.
But these titans of the typeset have taken to high technology.
While a certain segment of the NBS membership are purists, I think it's safe to say that many were attracted to numismatic literature for the knowledge contained within. I think that's also true of most of The E-Sylum readership. I still love my library, but I'll take my numismatic information in any form I can find it in.
Congratulations to Jeff for a great, well-balanced article, and also to those quoted, E-Sylum readers all.
