The William H. Gass Papers consist largely of his own manuscript material: manuscripts and proof material toward his books, drafts of various stories, essays, and reviews, interviews, and a miscellaneous assortment of notes and other materials. Also present is a substantial amount of professional correspondence, primarily with universities, magazines, and publishers, as well as with his colleagues in academia and in the literary community.

The Charles Johnson Papers hold both published and unpublished work from the author spanning nearly six decades. The collection brings together manuscripts, drafts, correspondence, artwork, and ephemera and serves as a testament to Johnson’s wide-ranging career as a public intellectual.

The Shirley Seifert Papers consists of one setting copy of Let My Name Stand Fair by Seifert, correspondence concerning its purchase, and one program.

The Jarvis Thurston Papers consist primarily of correspondence relating to Washington University's Department of English and its visiting writers program. The most significant part of the Thurston collection is the correspondence from James T. Farrell to Thurston and Van Duyn. These letters are of a more personal nature and often discuss literary matters such as Van Duyn's work. A small group of manuscripts, notably two drafts of a Thurston short story, "The Cross," is also included.

The John Updike Papers consists of materials toward interviews about Updike in Life Magazine (November 4, 1966) and Time Magazine (April 26, 1968) and one poetry draft by Updike.
