"This work is the outgrowth of an effort on the part of the editors of McClure's Magazine (who) decided a few years ago to publish a detailed narrative of the history of the growth of a particular trust. The Standard Oil Trust was chosen for obvious
reasons. It was the first in the field, and it has furnished the methods, the charter, and the traditions for its followers... Its vast
profits have led its officers into various allied interests, such as railroads, shipping gas, copper, iron, steel. It has led in the
struggle against legislation directed against combinations. Its power in state and Federal government in the press... is generally
recognised. The perfection of the organisation of the Standard, the ability and daring with which it has carried out its projects,
make it the pre-eminent trust of the world-the one whose story is best fitted to illuminate the subject of combinations of capital."
-- from The History of the Standard Oil Company, 1904
