The collection contains a series of manuscript poems (both typewritten and handwritten items) by Sitwell as well as some letters and miscellaneous items. Many of the manuscript poems in the collection are versions of one another, and several of them were published in Sitwell's first book, The mother and other poems (1915). The letters in the collection are from Sitwell to her cousin, and fellow writer, Joan Wake, and chiefly address Sitwell's writing. The miscellaneous items include pieces written by Wake on modern poetry in general and on her cousin's poetic stylings in particular.
