The William R. Perkins Library system has nine branches on campus. It includes a major collection of Confederate imprints.
Bostock Library, named for board of trustees member Roy J. Bostock, opened in the fall of 2005 as part of the University's strategic plan to supplement Duke's libraries. It contains 87 study carrels, 517 seats, and 96 computer stations, as well as 72,996 feet (22,249 m) of shelving for overflow books from Perkins Library as well as for new collections.

It contains 400,000 volumes, as well as various periodicals and other materials to support the study of theology and religion. The library is the host institution for the Religion in North Carolina Digitization project, a collaborative digitization project with Wake Forest University and the University of North Carolina at Chapel Hill, due for completion in 2015.
