The bulk of this massive collection consists of letters written by secretaries of the Board to its missionaries and others; and letters received by the Board, largely from missionaries in the field. Also included are records of organizations associated with the Board and miscellaneous manuscripts, largely personal papers and photographs of individuals connected with the Board. The chief importance of the papers probably lies in the immense amount of information--social, political, and geographic, as well as religious--which they contain about those regions of the world in which the Board's missionaries operated., Established in 1810, the American Board of Commissioners for Foreign Missions (ABCFM) was a Christian missionary society that sent missionaries to foreign countries. This is a collection of documents pertaining to the missions in Siam (Thailand), Singapore, Indian Archipelago and Patagonia, dated between 1831 and 1838. It includes correspondence between missionaries in the field and the administrative officers, and some administrative records.
