Bobby Butler scanned the maps added in 2014. Joost Dupon of the Map Collection did most of the scanning and image preparation. The Digital Media Laboratory let Map Collection staff use its Contex scanner, and Dale Mertes of the Digital Media Lab provided an enormous amount of assistance. Several people contributed to the construction of this Web page. If you use the images in a publication, we expect that you will mention that the original maps-and the files-are from the University of Chicago Library's Map Collection.

It also allows download of jpeg versions of the files (click 'Export'). Luna, like Zoomify, allows you to zoom in and out and to move around. You can also see the files through Luna. Zoomify requires Flash and so won't work on many mobile phones. Zoomify breaks the original tiff files into tiny jpegs, so you can zoom in and out and move around quickly and efficiently. Click on the thumbnails below to see the files in a program called Zoomify. You can access these files in two different ways:

The maps were scanned at 400 dpi using NextImage software and were saved as tiff files Nonetheless, these maps contain information that exists in no other form.

Some are rather difficult to read, and we have been unable to locate a completely clear legend for the land use set. We acknowledge that many of the maps linked on this Web page, compiled for internal agency use, are not cartographic masterpieces. Thus, the 1928-1929 set of USGS topographic maps of the Chicago area gives an extraordinary sense of the texture of the built environment that later editions do not. These maps differed from what would become the standard 7.5 minute sheets in showing individual buildings, at least in a stylized form, even in urban areas.

Geological Survey, in conjunction with the Illinois Geological Survey, produced prototypes of its new 7.5 minute 1:24,000 series of topographic maps for a large part of northeastern Illinois.

Army Corps of Engineers, the Chicago Park District, and the Cook County Forest Preserve District. Other 'descriptive' maps focused on the work of long-existing government agencies, for example, the Sanitary Commission, the U.S. Other government maps from the 1920s, 1930s, and 1940s were essentially descriptive, for example, the Chicago Regional Planning Association's maps of industrial employees, subdivided land, and rail commutation time.

Many features included in on this map-certain highways and rail lines, for example-not to mention a population of 3.8 million in 1965-never quite came to pass, but the postwar city of freeways, new government-built rapid-transit lines, and large-scale urban renewal was sketched out in detail for the first time. As World War II began to draw to a close, the Chicago Plan Commission compiled maps in which major postwar planning efforts were proposed, and in 1946 it published the first detailed land use plan for Chicago. In the 1930s, government agencies, having acquired a mandate from the New Deal to try to alleviate urban poverty, produced maps that showed the geography of substandard housing, redlined areas, population loss, and relief distribution. In 1922, for example, the Chicago Zoning Commission, in order to facilitate the creation of Chicago's first zoning law, compiled the first land-use map of Chicago. Many of these maps were compiled to assist in the implementation of particular programs. This Web page provides access to some government maps of Chicago from this period that are held at the University of Chicago Library's Map Collection.

Cartographic materials of various sorts were one of the byproducts of this growth. Government Maps of Chicago in the 1920s, 1930s, and 1940sĭuring the 1920s, 1930s, and 1940s, there was a slow growth in the planning role of municipal governments in many large American cities, including Chicago.
