The papers consist mostly of manuscript and typescript letters, with some manuscript and typescript compositions; including two letters in the hand of Ivor Novello. The bulk of the letters are to Ivor Novello from friends and fans, especially fellow theater performers, concerning Novello's shows and social events. The correspondence of Edward Marsh, Novello's long-time patron, includes letters concerning Novello's assignment to do performance propaganda for England in Stockholm and general personal letters which often mention Novello. Christopher Hassall's correspondence is chiefly about his inheritance from the Novello estate and royalties on work created with Novello. The compositions are largely about Novello, except for one piece, in French, about John Hassall. The papers also include further material about Novello's estate, including a list of borrowed artwork and notes from a meeting of trustees.
