MPL has added a new index to its online collection of Finding Tools!
The Wisconsin Land Ownership Map and Plat Book Index is a listing of the plat books and maps in the MPL collection that show property ownership. These books and maps are particularly useful to genealogists and house historians as they give the names of the owners of individual land parcels.

Ranging from 1858 to the present, the collection includes all of Wisconsin's counties. Note that the library does not have a plat book or map for each county for every year.
The index is arranged alphabetically by name of county. Each entry includes the name of the county covered and the year during which the map or book was published. Also included are the call number and location code, which assist the librarian in locating the volume within the collection.
All of the resources in the index can be found in Central Library's Humanities Department. Please contact the Humanities Desk at (414) 286-3061 for more information.
