Welcome to the Jost Bürgi Research Library

The Jost Bürgi Research Library at the Horological Society of New York is among the largest horological libraries in the world, containing over 25,000 items on all aspects of the study of time and timekeepers. The collection includes a vast array of books, periodicals, audiovisual materials, rare ephemera, and more.

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.
