The 2,000-square-foot library is located on the fifth floor of the General Society Building on Midtown’s historic “club row.” From its double-height arched windows, patrons can enjoy views of the Harvard Club of New York City.

The HSNY Library also hosts educational exhibits and special events. The collection was generously donated by Fortunat Mueller-Maerki and named after innovative Swiss clockmaker Jost Bürgi.
