The C. S. Lewis Collection is a collection of C.S. Lewis's books and letters purchased in 1997 from Dr. Marvin W. Anderson, the late professor of church history at the Southern Baptist Theological Seminary. According to Lyle Dorsett of Wheaton College, "It is one of the finest personal collections of Lewisiana that I have seen. Only one man in the U.S. has a better personal library of Lewis volumes."
