The Duke University Libraries are the shared center of the university's intellectual life. The William R. Perkins Library, Bostock Library, and David M. Rubenstein Rare Book & Manuscript Library comprise the university's main library complex, which is joined on East Campus by the Lilly and Music Libraries, and by the Pearse Memorial Library at the Duke Marine Lab. Together with the separately administered libraries serving the schools of Business, Divinity, Law, and Medicine, they comprise one of the nation's top 10 private research library systems.
