Sanborn Digital Maps: New Mexico This link opens in a new window
Sanborn fire insurance maps are valuable historical tools for a wide variety of researchers--essentially anyone who wants to learn about the history, growth, and development of American cities, towns, and neighborhoods. These maps are large-scale plans containing data that can be used to estimate the potential risk for urban structures. * This includes information such as the outline of each building, the size, shape and construction materials, heights, and function of structures, location of windows and doors. The maps also give street names, street and sidewalk widths, property boundaries, building use, and house and block numbers. Seven or eight different editions represent some areas. The New Mexico collection contains 209 maps from 51 cities, spanning a period from the 1880s to the late 1940s.
