Another method to find out if there has already been some research done on your building is to log into the Illinois Historic Preservation Agency’s HAARGIS (Historic Architectural and Archaeology Resources Geographic Information System). The site consists of a GIS-created map that allows its viewer to search a property by address, common name, or geographic location. Rock Island has approximately 1,000 entries on this database. You might find architectural details, historical information or photographs for your building.
