These pages are lists of the census microfilms for the state of Illinois. You can find your enumeration district numbers (EDs) on “A Look At Cook” or on Steven Morse’s site, or on the National Archives web site. Then use this series of pages to find the right microfilm number to order the film from LDS or NARA. The districts are not filmed in order on each film so it is not easy to locate the right film by reading the film descriptions. These pages, however, are sorted by Illinois county, then enumeration district, so you can find the right film number easily.
