Antique Book Help? I don't know anything about it. Thank you in advance.?

Go to this site: www.abebooks.com (or perhaps it's abebook, try both!). It's a kind of ebay for individual booksellers selling out-of-print and rare books. Just type in the name and it'll bring up all the copies for sale, with all their prices. (it's not part of ebay by the way).
