There are many brief works on Robert Morrison, and he is mentioned in virtually every work on missions in China. However, there is no modern scholarly biography. The best available is BroomhallMarshall, Robert Morrison: A Master-Builder (London: Livingstone Press, 1924). Another useful work is his widow's biography of Morrison. See Elizabeth Armstrong Morrison, Memoirs of the Life and Labours of Robert Morrison, D.D., 2 vols. (London: Longman, Orme, Brown, Green & Longmans, 1839). The latter is somewhat difficult to find in print but is available on microfiche from Interdocumentation Corporation in Leiden, Netherlands. The main depository of Robert Morrison materials is the collection of London Missionary Society materials at the Library of the School of Oriental and African Studies of the University of London. There is a quantity of other material scattered around the world, which at a later date will be brought together in a collected edition entitled The Papers of Robert Morrison.
