Have you ever wondered about the credited quotes in Webster's Third New International Dictionary? Webster's assures us they are "contemporary quotations from well-known people and publications." Close examination of the dictionary itself, however, reveals they are a bewildering diversity, not necessarily either "contemporary" or "well-known".
