The Office for Metropolitan History maintains a collection of 40,000 4x5 film negatives, 18,000 photographs, and 8,000 architectural drawings, many of which date back to the late 19th century. In the normal course of business, we have independently humidified, conserved, repaired and protected about 9,000 vintage blueprints, renderings and other architectural drawings.

In September 2001, the Office for Metropolitan History was the firm called by the New York City Department of Design and Construction to locate architectural records for the nine buildings damaged in the World Trade Center collapse that were considered in danger of falling or where people were thought to be trapped. We located original drawings for seven buildings within 36 hours.
