The Robinson Atlas will help you to date the construction of a building (e.g. it appears in the 1905 Baist Atlas atlas but not in the 1887) and give you a picture of neighborhood development. These maps also show the legal description (addition name, lot, and block numbers) of your building, which is necessary for locating many historic building records.
The Central Library will temporarily close to the public beginning Sunday, Jan. 22 for approximately two weeks. Holds will be available at the Curbside and Holds Pick Up Window. More information.
