Rosenbach Museum & Library

What Rosenbach Museum & Library does

The Rosenbach Museum & Library is a Philadelphia-based nonprofit cultural institution founded in 1954 that operates a museum and research library housing approximately 400,000 rare books, manuscripts, and fine and decorative arts objects. Its holdings include the manuscript of James Joyce's Ulysses, a first edition of Cervantes' Don Quixote, the Marianne Moore papers, and a substantial Lewis Carroll collection, and it is affiliated with the Free Library of Philadelphia.

The institution operates a Koha-based library catalog branded "Rosy" and a discovery layer branded "CatalogAccess (Phil)," and has invested in digital initiatives such as an IMLS-funded online catalog and the Marianne Moore Digital Archive partnership with the University at Buffalo. It runs recurring public programming including the annual Bloomsday Festival, held since the 1990s, alongside exhibitions, tours, and a museum shop.

Its business model is that of a 37-employee cultural nonprofit: revenue is generated through admissions, memberships, individual and corporate donations, foundation and government grants (including IMLS, William Penn Foundation, and Wyncote Foundation), ticketed programs, and retail, with the 2026 William Penn Foundation grant of $750,000 earmarked for capital upgrades to the historic townhouse facilities.
