Maps and atlases are basic tools for the geographer. Because of their sometimes unusual size and shape, they are often housed in special collections. Coverage in atlases can extend far beyond the reach of familiar reference works, such as the Atlas of the World, 16th ed. (New York: Oxford University Press, 2009), to provide information on population, trade, history, water resources, and so on. Additionally, GIS (Geographic Information Systems) software may be available for creating your own maps.
