Ah, here's another good one: Between the Dollar-Sterling Gold Points by Lawrence Officer, Cambridge Press. This one will cost you about 75 shares of Kimber. But it's excellent as well.

It was in the bibliography of the Goldwatcher, but they got the title of the book incorrect. The correct title is above. I have combed many a bibliography looking for gems such as these!

There are other books, but these are the two best about the subject of Hysteria's query.
