American Century Dictionary

Originally developed by Oxford University Press's Dictionary Department and edited by noted lexicographer Laurence Urdang, THE AMERICAN CENTURY DICTIONARY is a totally new dictionary created for American English. Its unique features include:
-- the latest new words and acronyms, such as NIMBY, telecommute, and grunge
-- thousands of colloquial and slang expressions, such as legit, yuck, and zilch
-- up-to-date computer and technical terms, such as ASCII, e-mail, fax, and virtual reality, as well as new terms from medicine and business
-- special easy-to-use organization -- all entries, including prefixes, abbreviations, foreign words, and biographical and geographical names, are arranged alphabetically in one section
-- separate quick-reference tables: countries, states, state capitals, area and ZIP codes, presidents, and more.
