The first edition of The Century Dictionary and Cyclopedia was published from 1889 to 1891 by The Century Company of New York. It was edited by Sanskrit scholar and linguist William Dwight Whitney, with Benjamin Eli Smith's assistance. After Whitney's death in 1894, supplementary volumes were published under Smith's supervision, including, The Century Cyclopedia of Names (1894) and The Century Atlas (1897). A two-volume Supplement of new vocabulary, published in 1909, completed the dictionary. The completed dictionary contained over 500,000 entries, more than Webster's New International or Funk and Wagnalls New Standard, the largest other dictionaries of the period. Each form of a word was treated separately, and liberal numbers of quotations and additional information were included to support the definitions. The Century Dictionary was admired for the quality of its entries, the craftsmanship in its design, typography, and binding, and its excellent illustrations. It has been used as an information source for the makers of many later dictionaries, including editors of the Oxford English Dictionary, who cited it over 2,000 times in the first edition.
