The collection largely comprises letters addressed to Sassoon although there are few other recipients such as Glen Byam Shaw and Georgiana Theresa Thornycroft, Siegfried Sassoon's mother. There are also some postcards; draft and unpublished copies of poems; bills; and other related papers.

A collection of 1094 letters, postcards and other items known as 'Sassoon's residual correspondence' although it does also include a number of items addressed to other persons particularly to his wife, Hester, and his mother, Theresa Thornycroft.

Letters and related items, mostly addressed to the editors of the Cambridge Review, and predominantly to Peter Hawkes. Some letters were intended for publication; most of the others concern the contribution (or otherwise) of articles and book reviews.

Re personal news, comments on Stephen Tennant's health and effect of illness on his emotions, congratulations on engagement.
