This new Roget edition of the renowned Webster's New World(TM) Thesaurus features an all-new thematic index, based on Roget's original categories, that provides a new means of access to the body of the thesaurus without sacrificing the proven usefulness of its A-Z structure. New introductory material reintroduces Roget's organizational technique to a new generation of thesaurus users. A useful and entertaining appendix provides lists of important terms grouped by their endings, such as -cracy (government types), -ology (fields of scholarship), and more.
