The Real Estate Record and Builders’ Guide was published from 1868 to 1922, and the Baruch College Archives, as part of our Durst Collection is fortunate to have the volumes from 1890 to 1909. These volumes include a weekly report on building activity in New York City and the surrounding areas. The expansion of the city is phenomenal and is chronicled on every page of the volumes. The incorporation of Greater New York in 1898 spurred increased building activity and expansion of the city into the outer boroughs. A sampling from the volumes provides a glimpse of the economic activity in New York City at the turn of the twentieth century.
