Detailed large-scale building and land-use maps of 148 Maine towns and cities.
Combined with other sources such as city directories, photographs, small-scale maps, census records, genealogies, and statistical data, the Sanborn maps provide an unparalleled picture of life in American towns and cities. The maps provide a wealth of information, such as building outline, size and shape, windows and doors, street and sidewalk widths, boundaries, and property numbers. Plans often include details on construction materials and building use; and also depict pipelines, railroads, wells, water mains, dumps, and other features likely to affect the property's vulnerability to earthquake, fire, and flood.
