Archives and Collections
The Geography Map Library contains approximately 400,000 flat sheet maps, large-format atlases, historical aerial photographs, gazetteers, and a reference collection dedicated to geography, cartography, and Los Angeles history. The Map Library is selective depository library of the United States Geological Survey (USGS), the National Imagery and Mapping Agency, and Natural Resources Canada. As a result, the library’s resources are both varied and extensive. Holdings include a comprehensive collection of USGS topographic maps from all states, historical and thematic maps of the United States and the world's major regions, historical aerial photographs of Los Angeles County and the San Fernando Valley, and atlases and gazetteers, such as National Atlas of the United States of America, Atlas of California, and California Water Atlas. The Map Library also contains one of the largest collections of Sanborn Fire Insurance atlases (1884-1963) in the western United States. These large, historical atlases document, in fine detail, historic land use in most of the major cities and commercial areas on the West Coast, as well as in a number of cities and towns in other regions of the United States.
