English repositories are gradually organizing and indexing their large holdings of missionary material under the guidance of trained archivists. The general practice is not to bind their manuscripts, but to place them in boxes arranged chronologically by country or, where missionary activity has been intense, by mission station within the country. Each box contains an index for material in that box. The larger societies have files on individual missionaries and the London Missionary Society has a painting or photograph of each individual it sent into the field. Gradually, comprehensive indexes to the whole archive are being prepared and registered with the National Register of Archives (Quality House, Quality Court, London W.C. 2). The National Register is mimeographing these guides, but in limited quantity.
