There are original documents from the period 1746-1861, transcripts made by John Norman Libbey, Principal of the Moravian College at Fairfield, from the archives of the British Province in London and from those of Herrnhut in Germany, and papers and reference tools illustrating Libbey's work as an historian of the Moravians. These records shed light both on the European background of the Church and on its development in Britain and Ireland. Most notable is an almost complete set of the Moravian headquarters diary, consisting of an 18th-century English translation for 1747-1753 and 1755-1764, and a German version for 1747-1754. Libbey's working papers (Eng MSS 1054-1087) include a History of Unitas Fratrum in four notebooks, lists of English ministers and other Moravian labourers up to 1900, analyses of the contents and authors of Moravian hymn-books from 1741 to 1940, and correspondence with English, American and German Moravian scholars, 1900-1941. This collection includes transcripts of material at the Moravian Church Archives (Provincial Archives) in London: see http://www.moravian.org.uk/; and the Herrnhut archives: see http://www.archiv.ebu.de/.
The items are individually numbered English MSS 110, 871, 897-898, 905, 910, 945-950, 965, 1054-1087, 1244 and 1276.
