This collection documents the life of Irish author Monk Gibbon through correspondence and manuscripts held in the papers of two of his peers: his bibliographer Alan Denson and one of his early publishers Alan Steele. Also included are portraits of Gibbon and his family, which may have belonged to Denson.

Alan Denson's correspondence from Monk Gibbon concerns their collaboration on Letters from AE, as well as Denson's proposal to write Gibbon's bibliography. Gibbon's later letters contain substantial enclosures of copies of his work for inclusion in the bibliography. There is a single response from Denson in the correspondence, an open letter to Gibbon addressing a disagreement between the two in July 1987, just months before Gibbon' death. Denson's papers also include articles by and correspondence from other writers concerning Gibbon.

Alan Steele's correspondence and manuscripts by Monk Gibbon were all enclosed in Steele's collection of Gibbon books. The letters discuss Steele's publication of Gibbon's book (possibly Seventeen Sonnets) and also hint at a long-running literary exchange between the two.
