The collection of the Keats-Shelley House includes some four hundred autograph (and occasional typewritten) manuscripts, comprising mostly letters, but also diaries, memoirs, and literary manuscripts. Key figures represented in the collection include John Keats, Percy Bysshe Shelley, Mary Shelley, Lord Byron, Joseph Severn, Leigh Hunt, Robert and Elizabeth Barrett Browning, Oscar Wilde, and Jorge Luis Borges.


The collection has been amassed since the foundation of the Keats-Shelley Memorial Association in 1903, with a large number of items donated to the House over the decades, and several key manuscript acquisitions made in recent years.
