Upper Mississippi Valley map reproductions (1829, 1840), undated

The bulk of the local history series consists of maps. Maps in this subseries include neighborhood, city, county, Quad Cities area, state, regional, and national maps, with a particular focus on the Midwest and Mississippi River. Within individual folders, maps are arranged in chronological order, with undated maps at the end of the folder. Some of the maps are photocopies; in these cases, the item is arranged chronologically according to the date of the original map, but the date of the photocopy has been used to calculate the date range of the subseries.
