Plat books, or cadastral maps, contain township maps by county. They illustrate the location of property boundaries and label major landowners. Acreage information and local landmarks are also shown. Public Land Survey System descriptions are included in the introduction of each book.
The PDFs below include holdings for plat books of Minnesota, North Dakota, and South Dakota. All include counties and years.
When an asterisk (*) is used, this indicates the plat book is archived in the Lass Center on the second floor.
