The Mineral Point Library Archives holds a large collection of maps ranging from recent plat maps to early territorial maps. A large part of the collection is based on the 1980 donation by Robert Neal.
The Map Index may be searched by map title, date, type (topographical, plat, aerial, etc), and cartographer (wherever possible). The Map Index currently has 217 entries and is regularly updated. Each entry has an inventory code number for ease of retrieval.
Please contact the Archives with your questions. We would be glad to help.
