The centerpiece of the library system is the Sterling Memorial Library, a Collegiate Gothic building constructed in 1931 and containing the main library offices, the university archives, a music library, and 3.5 million volumes. The library is also known for its major collection of rare books, housed primarily in the Beinecke Rare Book and Manuscript Library as well as the Cushing/Whitney Medical Library, the Lillian Goldman Law Library, and the Lewis Walpole Library in Farmington, Connecticut. Many schools and departments at Yale also maintain their own collections, comprising twelve on-campus facilities and an off-campus shelving facility.
