The Encyclopedia of World Biography (EWB) Index is designed to serve two purposes. First, it locates information on thousands of specific topics mentioned In the encyclopedia—persons, places, events, organizations, institutions, ideas, titles of works, inventions, and schools, styles, and movements In an art or a field of knowledge. Second, it classifies the subjects of EWB articles according to shared characteristics. Vocational categories are the most numerous—for example, Artists, Authors, Military leaders. Philosophers, Scientists, Statesmen. But there are other groupings, besides the vocational, bringing together disparate people who share a common characteristic—for example, Assassinations, Child prodigies, immigrants.
