Why would you want a thesaurus when you can have a Synonym Finder?
The best place for synonyms around. I've never quite figured out what thesauri are supposed to accomplish...all the indexing, cross-referencing, antonyms...
It's useful for learning about words, but what I need as a copy editor (and what a lot of people need, I think) is a book that gives you options. As in lots of synonyms. Which the Synonym Finder does.
