"The Marion E. Wade Center of Wheaton College, Illinois, houses a major research collection of the books and papers of seven British authors: Owen Barfield, G.K. Chesterton, C.S. Lewis, George MacDonald, Dorothy L. Sayers, J.R.R. Tolkien, and Charles Williams. These writers are well known for their impact on contemporary literature and Christian thought. Together they produced over four hundred books including novels, drama, poetry, fantasy, children's books, and Christian treatises. Overall, the Wade Center has more than 11,000 volumes including first editions and critical works. Other holdings on the seven authors include letters, manuscripts, audio and video tapes, artwork, dissertations, periodicals, photographs, and related materials. Any of these resources may be studied in the quiet surroundings of the Kilby Reading Room."
