This great new resource is now available to researchers looking for specific historic maps or specific features of maps. It includes MDAH maps as well as those in other repositories, such as the Library of Congress, the National Archives and Records Administration, and various universities and libraries. The maps have been described with fifteen different categories (such as title, situation date, and geographic coverage). Over 850 maps have already been added to the database with more to come. The database also includes links to digital images where they exist.
