Between 1939 and 1941, the Works Progress Administration collaborated with the New York City Tax Department to collect photographs of every building in the five boroughs of New York City. In 2018, the NYC Municipal Archives completed the digitization and tagging of these photos. This website places them on a map. Zoom in! Every dot is a photo.

This is fun to browse through. "From an initial gift of eight prints and one drawing, The Museum of Modern Art's collection has grown to include 150,000 paintings, sculptures, drawings, prints, photographs, architectural models and drawings, and design objects. MoMA also owns some 22,000 films, videos, and media works, as well as film stills, scripts, posters and historical documents. The Museum's Library contains 300,000 books, artist books, and periodicals, and the Museum Archives holds approximately 2,500 linear feet of historical documentation and a photographic archive of tens of thousands of photographs, including installation views of exhibitions and images of the Museum's building and grounds."
