The Maps Unit of Special Collections at the Richard J. Daley Library has an extensive collection of print aerial photographs of Chicago and the surrounding counties. Publicly available are Chicago photos from 1968, 1973, 1994 and from the six county area we have photos from 1980, 1990, and 2001. Other years are in the collection and may be accessed by contacting the map librarian.
In addition we have 2002 and 2005 USGA orthographic aerials and 2004, 2005, and 2006 NAIP images. These require that you contact the Maps Unit and arrange an appointment for copying the files.
