U.S. Geological Survey Maps
As a depository for federal documents, the Map Collection receives USGS topographic maps covering the entire United States. The most familiar are the 7.5-minute, 1:24,000 scale maps. These maps are revised periodically and the Collection retains earlier issues.
The Collection also contains 15-minute, 1:62,500 scale maps. This was the scale at which much of the country was mapped before the 1:24,000 scale became standard during the 1950's. Alaska is still being mapped at this scale.
In addition, much of the U.S. has been mapped by the USGS at scales of 1:50,000, 1:100,000, and 1:250,000. Maps and charts covering the United States are also available at scales of 1:500,000 and 1:1,000,000.
International Topographic Maps
The Map Collection contains a large number of map series of foreign countries at various scales. We are currently evaluating the international topo map holdings and will post an updated guide to the collection soon. If you need immediate assistance with determining if we have topo series maps for your area of interest, please feel free to contact the Map Collection staff.
The Map Collection staff are currently in the process of creating digital versions of the index maps for many of our international series maps available for use in Google Earth. These indices include hyperlinks to high resolution scanned images of individual series maps.
The Map Collection holds many historical nautical charts and coastline maps. A list of those maps which are currently online can be found below.
The Library also has a recent (current through 1999) set of NOAA nautical charts covering the U.S. coastline and waterways. These charts are housed in the Mudd Library and can be retrieved through the Map Collection.
The 3,000+ volumes in the atlas collection include world, regional, national, state, and urban atlases, as well as a large number of historical and other thematic atlases.
Most pre-19th century atlases are housed in the Beinecke Library, although the Map Collection has a number of reproductions and facsimiles of early atlases.
