A General Overview of Our Collections
Aerial Photographs The Map Library maintains a comprehensive collection of aerial photographs for all Illinois counties , ranging in date from the late 1930s to 2005. Finding photos taken from the late 1930sto the early 1980s for an area in Illinois requires consulting photo-mosaic indices for the relevant county and years. The process of finding aerial photos for a pre-determined area is somewhat easier after 1988 because a single index can be used for all years. Aerial photographusers are responsible for using indices to identify the photographs that they need to examine and completing a photograph request form .

Sanborn Fire Insurance Maps – Sanborn mapswere made to assist insurance underwriters in determining fire insurance rates for individual buildings by examining the buildings’ construction methods, heat and lighting sources,manufacturing uses, and the same attributes of nearby buildings. The maps primarily provide information on the downtown areas of cities and adjoining residential areas. They are especially useful in providing a record of urban development from the 1880s through the first half of the twentieth century. Family historians other genealogical researchers may also find them useful for verifying addresses of homes and family businesses.
Topographic Maps – The Map Library offers comprehensive topographic coverage of all states by the United States Geology Survey . U.S. coverage includes the following scales: 1:24,000; 1:62,500; 1:100,000; 1:250,000. (1:24,000 scale is the most detailed;1:250,000 is the least detailed.) There are individual state indices for the 24,000 and 62,500 series. These maps provide information on topography, transportation, relief (differences in elevation), drainage systems, and other physical and cultural features.The Library also has a comprehensive topographic coverage of other regions and nations of the world. Generally, coverage available for immediate consulation in the Map Library will be at the scale of 1:250,000.More detailed topographic maps are housed at and can be requested from the Oak Street Library Facility .
U.S. County Plat Maps – Plat books are atlases that show land ownership for rural areas and generally feature one township per page with a focuson rural property ownership.
