MADISON, Wis. (AP) -- Wisconsin Historical Society officials say they now have more than 3,000 digital versions of rare maps and atlases online. The online catalog was helped by the Caxambas Foundation, which started donating in 2009 for the cataloging, preservation and digitization of the maps. According to the historical society, it has 25,000 maps altogether but the collection had previously been neglected because the maps required specialized handling that most staff couldn't provide. The University of Wisconsin-Madison contributed staff to catalog several hundred of them, but at the time of the first donation thousands of maps could only be found through an antiquated card catalog. Hundreds more lay in random piles. The donations also enabled catalogers to describe more than 4,000 maps and atlases for the campus online library catalog.
