Historical County Plat Maps from South Central Wisconsin and Early Madison City Directories is a collaborative project completed by the University of Wisconsin Digital Collection Center and Madison Public Library.
This digital collection of historic plat books and atlases provides accessibility to early information about South Central Wisconsin, specifically Columbia, Dane, Portage and Wood counties. A variety of the oldest plat books and atlases were chosen because of their frequent use and delicate condition. They are widely used by the public for local history and genealogy and even for those trying to find out why a street got its name. The historical plat books help people to trace neighborhoods and streets from what was once farmland.
