The CSUN Map Library holds a research-level collection of approximately 400,000 historical and government maps, aerial photographs, atlases, and geospatial data that support research on campus. While holdings are international in scope, the collection emphasizes Western Americana, particularly maps of California, Los Angeles County, and the San Fernando Valley. Patrons can find primary and secondary resources like historical road and tourist maps, planning and zoning maps, topographic maps, geologic and bathymetric maps, WWII maps from the Army Map Service, and maps from other federal agencies like the USGS, the Bureau of Land Management, and the U.S. National Park Service. The Map Library also contains one of the premier collections of Sanborn Fire Insurance Atlases in the country, including more than 4,000 detailed Sanborn survey maps from locations throughout the western United States, Canada, and Mexico.
The Map Library is a comprehensive service point whose staff provides subject expertise in cartographic resources, general and complex reference services, GIS research & technical support, and map cataloging. The Map Library Reading Room (Sierra Hall 171) is an open study space available to all patrons and includes a scholarly collection of books and atlases available for browsing only. If you have research questions or inquiries related to cartographic resources, GIS, ArcMap, or using maps as primary resources, please come by our Reading Room to speak with a staff member today.
