New York’s Oldest Library Expands Its Stacks Without Leaving Its Readers Behind
The New York Society Library has completed a phased renovation of its Upper East Side home, adding space for books, conservation, and members while keeping the institution open throughout the work. Founded in 1754, the library is New York City’s oldest, and its latest overhaul was designed to protect a rare civic role: a private library that still functions as a circulating collection with broad public access for reading and research.
The project, which began in 2024 and was the library’s first building-wide renovation since the 1980s, was led by Larson Architecture Works. It expanded the stacks to 12 levels, created a conservation lab, added study and events spaces, and introduced new staff offices on a lower level. A rare-books reading room was also part of the reconfiguration, along with storage for folios and semi-rare books that had previously been moved off-site.
Carolyn Waters, the library’s director and head librarian, said the renovation was shaped by a long-running problem: space. The institution has remained in its Italianate townhouse on 79th Street since 1937, even as its holdings and its membership continued to grow. “We were bursting at the seams,” Waters said, adding that the library serves readers from across the city and beyond, though it remains, at heart, a neighborhood institution.
That sense of use is central to the building’s identity. The library maintains roughly 300,000 volumes, many of them heavily handled and, in Waters’s words, “loved to death.” Unlike many research collections, its books can be checked out by members, even when comparable copies at institutions such as the New York Public Library or Princeton University would have to be requested on site.
The renovation also preserved the library’s role as a place to work. On a recent weekday morning, nearly every desk and table was occupied, including in the Green Alcove, whose panelling was salvaged from the library’s former home at University Place. Douglas E. Larson of Larson Architecture Works said the project responded to Waters’s insistence that the biggest challenge was not storage alone, but space for people.
The conservation studio is already active. Werner Haun was preparing a first edition of Thomas Paine’s Common Sense for Collective Witness: A Library for a Young Country, an exhibition that opened on 18 June and focuses on the library’s 18th-century materials. The renovation, in other words, is not simply about preserving a historic building. It is about keeping a living collection usable, visible, and in circulation — a rare proposition in a city where access to books has changed dramatically since the library first opened its doors.
