The papers consist primarily of his official correspondence as archbishop of Canterbury (vols. 1-271), although there are a few volumes of correspondence and sermons covering his earlier career and his retirement (vols.272-81, 288, 327). The collection include a few papers particularly on Anglican-Methodist unity after his retirement. The collection also includes some correspondence and recollections of Fisher acquired by Dr. Edward Carpenter, dean of Westminter, during his preparation of the archbishop's biography (vols. 272, 274, 278, 328).
The official papers cover the whole range of Archbishop Fisher's concerns, from international affairs to Canterbury diocesan business. The bulk relates however to administration of the Church of England at home and Anglican Communion affairs abroad. Fisher took a close personal interest in the establishment of independent Anglican provinces overseas, particularly in Africa, and this interest is reflected in the papers. At home Fisher's involvement in administrative reform is amply demonstrated by the voluminous correspondence on Archbishops' Commissions, canon law revision, Convocation and Church Assembly business. On a more personal level Fisher's close interest in the restoration of Lambeth Palace after wartime bombing is evident. In addition his singular obsession with marriage discipline runs as a constant refrain through the papers.
Apart from Church of England affairs, the papers shed light on many important aspects of British post-war political, social and colonial history. There are files on such matters as birth control, capital punishment, gambling, homosexuality, prostitution, areas in which the Church had as it were a vested interest. Fisher's interest in Africa led to considerable dealings with many leading political figures, from the Kabaka of Uganda to Sir Roy Welensky, and the papers are in general a valuable source for the history of the twilight years of Empire.
