This is very cool.

Old drawings and elevations are so much fun to look through. Take a look at this extensive catalog of drawings, photographs and brochures for NY apartment buildings Pre WW1.

I love the interior shots with their moodiness and available lighting. Some of the images were obviously "painted with light" and they are fascinating. This is a well done, easily navigated site that will keep you involved for quite a while.

NYPL Digital Gallery: "More than 1,300 digital images depict elevation views and floor plans for middle and upper class apartment buildings from New York City's pre-World War I residential building boom."
