The William Gaddis Papers consist largely of his own manuscript material: manuscripts and source material toward his books, drafts of various stories, published and unpublished, as well as essays, reviews, interviews, and a miscellaneous assortment of notes and other materials. Also present is a substantial amount of personal and general correspondence, primarily with family, friends, and fans. In addition, there is a relatively large amount of correspondence to editors, translators, and publishers, as well as correspondence with his colleagues in the literary community.
