|Papers covering a diverse range of topics and arranged into a single sequence prior to deposit in Cadbury Research Library. Some of the material in this series seems to have been presented to the Society and should belong in the Church Missionary Society Unofficial Papers collection (CMS/ACC) rather than with the official records of the organisation, but no documentary proof of this survives; it also includes some material from the CMS Overseas (Missions) Series. The items originally numbered CMS/Z1-Z12 and Z23 have been transferred to other series to which they belong. The surviving documents have been used too often by researchers to make it possible to revise the numbering of the definitive list so there are some gaps in the numbering (the sequence starts at Z13).
The sequence is particularly notable for its travel journals, language notes, early photographs and small selection of samplers and watercolours. Highlights include a pocket diary used by [the Right Reverend James Hannington, Bishop of Eastern Equatorial Africa] in the month leading up to his death in captivity 29 October 1885, a Chinese primer c 1800, a letter from Sir Arthur H. Hardinge, Consul-General, Zanzibar concerning harbouring of slaves on mission estates and manuscript notes written by Mahatma Gandhi in an interview with Rev K. W. S. Jardine, November 1938.
