 Propriété de terres historiques et Atlas de référence, États-Unis, 1507 à 2000

Cette base de données est une collection de cartes et d’atlas des États-Unis et du Canada d’aujourd’hui, et de diverses autres régions du monde.

This database is a collection of maps and atlases detailing land areas that comprise the present-day United States and Canada, as well as various other parts of the world. It contains a variety of maps and atlases created for different scopes and purposes, including land ownership atlases and bird’s-eye view maps. Land ownership atlases usually show the names of contemporary owners or occupants of land and structures. Some of the maps depict countries and wider geographical areas, while others depict counties, cities, towns, and smaller geographical areas.

More About Maps and Atlases:

Maps, atlases, and gazetteers are essential tools for family historians. Maps may be either topographical (emphasizing land forms) or historical (emphasizing historical events) in nature, though either type can show cultural features, such as the town and creek names that are so important for research. Public libraries and especially college and university libraries usually have good contemporary maps. Historical maps are sometimes more difficult to find. Genealogical and historical societies in the area you are researching are likely repositories for old maps. The Internet is also a good place to locate obscure maps.
