Steven Levy's "Crypto" [http://www.stevenlevy.com/index.php/books/crypto] is a good read on this topic if you're looking for something more in-depth.

$23 for a book from 2001 on an evolving topic? Surprised there's not a 2nd edition. Anything that includes the 2000-2010 decade as well?

It's extremely well researched and well written, with fantastic insight - well worth 23 USD - highly recommend.
