About this Collection

Sanborn Maps of Illinois, 1867-1970

Sanborn maps Sanborn maps were originally created to help fire insurance companies determine the risks associated with insuring properties. These large-scale maps were drawn at a scale of 50 feet to an inch. Because the maps were created over a century, they are useful in charting the development of cities and towns over many years.

Although this collection contains maps only from Illinois for the time period of 1867 - 1970, the Sanborn company created fire insurance maps for over 12,000 cities and towns across the United States, Canada, and Mexico. More information about the history of Sanborn fire insurance maps can be found at the Library of Congress website "Introduction to the Sanborn Map Collection."

This collection is available to CARLI Governing and Affiliate member libraries at no direct cost to the library.

Using this collection

Map Sets with Duplicate Dates
The maps in this collection were microfilmed from a collection held at the Library of Congress. This collection includes all maps submitted to the Library from the Sanborn Company as well as maps transferred to the Library from the Bureau of the Census. The Bureau of Census maps often contain corrections pasted onto the maps. An asterisk (*) at the end of the title indicates if a set of maps is from the Bureau of the Census.

New and Additional Sheets
Some sets of maps may contain the term "New and Additional Sheet" in their title. These maps are updated sheets that were created to replace sheets from previous map sets. The image of the sheet will refer to what sheet it replaces.

Volumes
Bound volumes of maps (approximately 100 sheets), were created for large cities. If you choose a city where the maps were separated into bound volumes, the volume is incidated in the title of the map set.

Key and Index Sheets
Map sets containing a number of sheets will also include a key and/or index. If present, the key and index sheets can normally be found at the beginning of a map set.

Key maps are "bird's eye" overviews of a city. Use the key to find the portion of the city you wish to view, and then look for the sheet/volume numbers printed on the key. The sheet/volume number will correspond to a specific sheet in the map set for that area of the city. Index sheets provide a listing of streets and important buildings (labeled "specials"). The index will provide the specific sheet number for the street or building.

Downloading copies of the maps
A high-resolution TIFF version of each map is available. The TIFF can be downloaded directly from the metadata for any image via the link in the Full Resolution metadata field. Download methods vary across browsers, but clicking or right-clicking on the link should prompt a download or "save as" option.
