Finding Maps by Call Number
The Earth Sciences & Map Library's collection is cataloged using the Library of Congress G-Classification call numbers, which arrange maps according to geographic areas. One way to retrieve map records from the Library's online catalogs is to search by "Call Number" phrase (e.g., G4363.S3 for Santa Barbara County, California).
NOTE: Call number searches will not retrieve all maps for a given geographic area. For example, a map of California with a city map of San Francisco on the back will be given a call number for the state (i.e. G4360 or G4361). Therefore, a call number search using the classification for San Francisco (G4364.S5) will not retrieve this map. Similarly, maps on microfiche/film, aerial photos, and maps in atlases cannot be found using "map" call number searches because they are assigned different call numbers from those assigned to flat maps.
