As well as the biography of Harold Roberts, written by John Lenton, that these papers were collected in support of, the Methodist Archives and Research Centre (MARC) holds a number of Roberts' own works. These include Belief in God (1936), Jesus and the kingdom of God (1955) and New Life in the Spirit (1962).
The MARC holds thousands of smaller collections of Methodist Ministers personal and official papers in addition to a large number of medium-sized personal collections relating to significant ministers, missionaries, laymen and educators, including the controversial nineteenth century leader of Wesleyan Methodism Jabez Bunting (1779- 1859), the pioneer of Methodist overseas outreach Thomas Coke (1747-1814), the lawyer and anti-slavery campaigner Thomas Allan (1774-1845), the China missionary and President of Conference Harold Burgoyne Rattenbury (1878-1961) and the minister and scholar Alfred Raymond George (1912-98).
