Beginning today, there will be on exhibition in the Treasure Room of the Widener Memorial Library a noteworthy selection from the library of Charles Sumner, of the class of 1830, who at his death in 1874 bequeathed his whole collection, one of the most valuable of the time, to the University. Among the most interesting of the books on view are a number of books of association with the great statesman, works formerly owned by personages famous in history, illuminated manuscripts of the 14th, 15th, and 16th centuries, and a collection of autograph books. Included in the books owned by great men of the past, all with the autograph of the owner, are John Bunyan's Bible, Racine's New Testament, and books of Napoleon Bonaparte, Louis XIV, and the Marquise de Pompadour.
