The Alfred Noyes Papers are composed mainly of the personal and professional correspondence of Alfred Noyes and his extended family as well as manuscripts and typescripts of Noyes's poetry and prose.

Among the correspondents represented are many notable social, political, and literary figures, including various signatories arranged by Noyes in an autograph collection. Within the professional correspondence are letters detailing Noyes's American lecture tours, reviews of his work, as well as "letters to the editor" drafted by Noyes.

The collection contains published and unpublished poetry, plays, short stories, novels and works of nonfiction. The majority of manuscript material in this collection is undated, but can be assumed to span the length of Alfred Noyes's career. Of note are an early manuscript version of "The Highwayman," the first edition manuscripts of The Secret of Pooduck Island and The Devil Takes a Holiday, and early drafts of Orchard's Bay and The Unknown God. The papers also include correspondence, research, and manuscript items pertaining to Roger Casement and Noyes's involvement in his case (1916-1958) as well as Noyes's controversial biography of Voltaire (1936-1942).

The collection also contains notebooks and diaries by Noyes (which feature both poetry and prose) as well as the diaries of members of the Noyes family (1874-1932). Also present are manuscripts of poetry (including tribute poems to Noyes), plays and fiction by authors other than Noyes (1898-1957), as well as manuscripts, typescripts, and several printed editions of nonfiction works either about Noyes or collected by him (1913-1958). The remainder of the collection is composed of musical scores inspired by Noyes's poetry; financial, genealogical, and other papers of Noyes and his family (1906-1961); photographs and other visual materials; audio recordings (including recordings of poems recited by Noyes); artifacts; printed materials; and press clippings.
