The AGS Library has over 520,000 maps of all types covering the world at a wide range of scales. Included are the major national topographic series, navigational charts detailing the Earth’s coastlines and a wealth of thematic maps treating the full range of physical and human factors. The oldest orginal map in the AGS Library holdings is the MappaMundi, by Venitian cartographer Giovanni Leardo, which dates from 1452. Over 600 maps can be view in the AGS Library’s Digital Map Collection. In addition, the Milwaukee, Wisconsin Sanborn Fire Insurance maps are also online here

The AGS Library has taken efforts to preserve many wall maps. Once the main stay of the classroom, these beautifully constructed maps are becoming more difficult to find. A sampling of wall maps held are available for viewing in the Wall Map Digital Collection.
Raised Relief 3D Maps
The AGSL has many of these three-dimensional models of the terrain. A raised-relief map or terrain model is a three-dimensional representation, materialized as a physical artifact, usually of terrain. When representing terrain, the elevation dimension is usually exaggerated by a factor between five and ten; this facilitates the visual recognition of terrain features.
The Library contains nearly 13,000 atlases ranging from 15th century editions of Ptolemy’s Geographia to the most modern compilations in paper or digital format.
The rare atlas collection consists of over 1,500 volumes of world and regional atlases. This collection contains classic world atlases, beginning with three versions of the 1573 Ortelius atlas and includes works by Gerardus Mercator, Gerard de Jode, J. J. Jansson, Willem Janszoon, Joan Blaeu, Nicolas Sanson, to name only a few. Also included is a collection of early Dutch, French and English marine atlases, and approximately 430 U.S. state, county and city atlases from the nineteenth century. The UWM Libraries are currently working on a “recataloging” project to get atlases cataloged online. Atlases may be searched in the card catalog or online using Search@UW.
The Milwaukee, Wisconsin Sanborn Fire Insurance Atlases for 1894 and 1910 are now online through the UWM Libraries Digital Collections. Click here to view them.
Some atlases not entirely cataloged online:
- U.S. Fire Insurance Atlases held at AGSL
- 19th Century U.S. plat atlases held in the AGS Library
- Note: AGSL has numerous other plat maps not bound in atlases. These are cataloged online or in the card catalog. See staff for assistance.
The AGSL collection includes over 120 globes, most on permanent display. Several globes are of historical value, including a 1613 Hondius globe and an 1831 matched pair of Wilson globes, plus a variety of thematic, special purpose, lunar, planetary and celestial globes. The largest and most spectacular is a rare example of the fifty inch “President’s globe,” produced by the OSS during World War II for President Roosevelt and Prime Minister Churchill.
