Website Search Box

The Smithsonian Institution, since the earliest days, has sent its researchers on expeditions to fulfill the mission of increasing and diffusing knowledge. These researchers usually relied on maps to plan and guide their quests. Ongoing efforts are being made to organize the maps that have accumulated over the years in the National Museum of Natural History and other collections. This website is a result of those efforts.

The catalog currently includes 34162 distinct maps covering 21181 subjects, with 33712 images available for viewing. You can search for details about any of the maps using four different methods.
