The General Society Library, which is the second oldest library in the city, includes a soaring, light-filled atrium that is used as a vibrant programming space by the General Society and other non-profits. Overlooking the Library is a striking iron wrought balcony area that houses the John M. Mossman Lock Collection, which contains more than 370 locks, keys, and tools dating from 2,000 BC, to the early 20th century. The Society’s archives and history date back to 1785. In addition to the Library and Lock Collection, the Society’s distinctive Member’s Assembly Room is also open to the public only on OHNY Weekend.
