The mission of the NOAA Library and Information Services is to ensure the delivery of scientific, technical, and legislative information to users, including NOAA staff, the general public, academia, industry, and other government agencies. The library's Historical Maps and Charts Web site contains over 20,000 maps and charts from the late 1700s to the present, some of the nation's earliest nautical charts, hydrographic surveys, topographic surveys, geodetic surveys, city plans, and Civil War battle maps. The Historical Map and Chart Project View or Download link contains the search interface, which allows users to look by keyword, region, type, year, or chart number. Once found, the charts and maps can be viewed in fine detail by zooming in and out and panning via the navigation buttons. Anyone interested in historical maps, nautical navigation, or similar subjects should thoroughly enjoy exploring what is offered on the site.
