The Institute is vested in the Council for World Mission, a Registered Charity number 232868 (formerly the London Missionary Society Corporation) as Trustees, and is managed on behalf of the Trustees by an Executive Committee. Little is known of the early history of the Institute. During the 1939-45 war the building was used by the Army, and the records (including the minute books), which were kept in the reading room, all disappeared and have never been traced. The building is a fine example of the Edwardian period, but its age means that there is a constant need for repair and maintenance work.
