Recently bought a rather large library of books, including many on the Lost Dutchman. Was curious which books are considered desirable, rare, sought after by collectors. I'm talking about more than simply well-known books, but things like self-published, brochures, obscure stuff. What are the books that Lost Dutchman enthusiasts are always on the prowl for? At some point I'll post al iist of what I have, for the time being I'm just curious what I should keep my eyes open for.
