The Noah Porter Papers consist of correspondence, writings, and miscellaneous papers brought together in 1980 from the Beinecke Rare Book and Manuscript Library, the Yale Treasurer's Records, and the autograph collections and miscellaneous collections in this department. There is much Porter material remaining in other collections, especially the Woolsey Family Papers.
Series I, CORRESPONDENCE, consists mainly of letters to and from Noah Porter, professor of moral philosophy and metaphysics and president of Yale College. About three-fourths were written while he was serving as president, and the rest were written earlier. There is hardly any continuity in this correspondence, but most letters deal with Porter's responsibilities as professor and president. Besides his correspondence, there are five letters by his father, the Rev. Noah Porter of Farmington, and a few letters to his father and his wife.
Series II, WRITINGS, consists of sermons, lectures, and notes of President Noah Porter, mainly originating during his presidency but including a few items from his student days at Yale. These are mainly manuscripts of published and unpublished works.
Series III, OTHER PAPERS, is a miscellaneous gathering of personal, professional, and presidential papers by Noah Porter and others.
