Mapping New York's Historical Photos

The New York Public Library has done a wonderful job in geo-rectifying thousands of historical maps from their collections. Now thousands of the library's historical photographs have also been geo-tagged.

OldNYC is a Google Map locating 80,000 NYPL historical photographs of New York to the closest intersection. Click on a marker on the map and you can view historical photographs of New York taken near that location. You can even use Google Maps Street View to explore the same views portrayed in the photos as they look in New York today.

OldNYC was created by the same team that built OldSF. OldSF is a similar map for San Francisco, which allows you to browse historical photos from the San Francisco Public Library collection.
