ESRI Data and Maps is a set of 5 DVD-ROMs containing many types of map data for the entire globe, with even more detailed datasets for the US. It includes StreetMap North America, which can be used for geocoding addresses in the US and Canada. These discs are located in a binder on
Stone Computing Center Reference Bookcase (map it) near the Computing Help Desk.
The Olin Library map room also has indexes of United States and International maps and GIS data sources.
