The College Archives also hold a Special Collections section which consists of a Rare Book Collection and the Jesuitana Collection (material by and about Jesuits). Noted collections include the papers of James Michael Curley, David I. Walsh, Louise Imogen Guiney, and Rev. Joseph J. Williams, S.J. There are also collections of material by and about Jesuits, college alumni, and friends of the college. The first naval chaplain to receive the Medal of Honor, Rev. Joseph T. O'Callahan, S.J., was laid to rest in the cemetery on campus and his award is kept in the college archives.
