Map & Atlas Collection

This collection is located on Floor 2 North and is served by the reference desk. Access to the over 1,500 atlases is through EUREKA, and the subject access to the 22,000 maps is only available through a card catalog in the Map and Atlas area. About half of the maps are US topographic maps for California and 5 other western states. The remainder consists of a broad variety of thematic maps such as geologic, physical, political, economic, social and historic. The majority of the maps are stored flat in map cases. Folded maps, such as road maps, and those in envelopes, such as physical maps, are stored in file cabinets. Large-size maps (generally 3' x 3') are mounted on wooden dowels and stored vertically in mobile roll files. Atlases are shelved in counter-high bookcases to facilitate ease of use.
