Dun & Bradstreet has been a major publisher of business information from its earliest iteration back in 1841. A corporate linkage directory, the Who Owns Whom Series lists corporate groups, ranging from companies with hundreds of members across all continents, to single-country groups with only a handful of members. Companies are listed alphabetically, with information on subsidiaries and parents, and country of incorporation for both parent and subsidiary. Recent editions still use the U.S. 1987 Standard Industry Classification system to categorize major trading activities.
