This database gives the coded directors and their companies as listed in the Directory of Directors for years 1882, 1892, 1902, 1912 (judged the most relevant for the census years) and also codes those linked to census records 1881-1911 for which their full census record is available in BBCE and linked to I-CeM. Record linkage match between DoD and censuses was 36% for 18,200 directors; but the database gives all DOD directors coded to business sectors, locations, and roles they played in each company.
