OldNYC provides an alternative way of browsing the extensive collection of Photographic Views of New York City, 1870s-1970s held at the New York Public Library. The site was created (in collaboration with others) by software engineer Dan Vanderkamof, who also built OldSF. Each of the websites is an interactive city map that contains dots at the locations where each photo was captured. Click on a dot to see historic photos of that location.
