The papers of James Rendel Harris include notebooks and newspaper cuttings relating to his research on folklore and the history of the Pilgrim Fathers' ship, the Mayflower; notebooks containing notes made by Harris about literature and biblical research, including topics such as 'the problem of evil' and 'twins'; and correspondence with friends and family. Regular correspondents include Herbert George Wood, Harris's secretary Irene Speller Pickard, Eric Wills, and John Major. Also well represented are letters between Harris and other contemporary scholars including E A Wallis Budge, James George Frazer, James Hardy Ropes, Lootfy Levonian, Henry J Cadbury, J de Zwann, Arent Jan Wensinck, Arthur Bernard Cook, William Charles Braithwaite and W J Rutherford. The collection also contains many of Harris's own copies of his books, essays and lectures, both published and unpublished. These volumes usually contain Rendel Harris's own bookplates, are often annotated, and occasionally enclose letters or other documents.
Also included in the collection are papers about James Rendel Harris collected by Irene Speller Pickard during the writing of her book, 'Memories of James Rendel Harris'; and papers belonging to John Major, the husband of Harris's niece, Katherine Ridges, which concern Harris and Major's shared research on the Egyptian origins of English place names. This was Harris's main research interest in the last years of his life. JRH/4 was catalogued in 2022, and comprises papers relating to Irene Speller Pickard's life and work relating to James Rendel Harris. These papers were donated by Alison Bush.
Whilst the date range for this collection is wide, the majority of the material dates from the late 19th and early 20th centuries. A small amount of material is dated earlier, including the early medieval manuscript fragments in JRH/1/6 and a 1680 property deed at JRH/1/1/6/44.
