Maps by Decade is part of The New York Public Library’s NYC Space/Time Directory.

Maps by Decade allows you to see NYC street maps from 1850 to 1950 superimposed on a current map of NYC.

You select the decade you’re interested in studying and then an area of New York City and you’ll be given some map options from the NYPL digitized map collections and you can opt to view it on the map or view it in the digital collection.
