It is rare to encounter such a well considered and helpful reference work. The thesaurus is based on the work of Peter Roget's original 1852 manuscript and is structured by six classes of word meanings which are later cross referenced in the index. This arrangement is useful for exploring ideas and is a great pleasure to use. The 150th Anniversary Edition includes new modern vocabulary and several interesting essays explaining the history, purpose and ideas behind the book. This item comes highly recommended as an excellent desk reference.
