The collection includes Edith Sitwell's manuscript versions of poems such as "The Outcasts", "At the Cross-Roads", and "The Queen of Scotland's Reply to a Reproof from John Knox", as well as drafts for many of the poems that would become Street Songs. Additionally there are notes, prose, and other writings.

The correspondence contains letters by Sitwell to friends, literary peers, and publishers. Of note are letters between Sitwell, D. O'Connell, SJ, and lawyer Ferdinando Bosi concerning Guido Masti, a caretaker of the Castle of Montegufoni, which Osbert Sitwell owned during World War II. The Sitwells credited Masti with the safe return of art masterpieces to museums which had been hidden at Montegufoni during the war, and they hoped to gain state recognition for Masti's efforts.

Also included is Sitwell's obituary as it appeared in The Observer Weekend Review (1964) written by Stephen Spender.
