A good way to find out what types of books are available for different counties is to search for the county on barnesandnoble.com. They take orders for rare and out of print books as the middleman for smaller booksellers around the country. (No, I don't have stock in Barnes & Noble! Amazon and others probably can get these too.) Some are probably available at your local library or online "free" with a premium Ancestry or genealogy.com subscription. Without doing this I would never have guessed that there was an Arkansas swamp land index! They list a number of items for Randolph County, AR: Index to the Arkansas General Land Office, 1820-1907 (covers several counties) Arkansas Land Patents: Randolph County (granted through 30 June 1908).
