"The Synonym Finder" is a thesaurus in dictionary form. There are no word definitions or pronunciation guides. Words are listed alphabetically, as they would be in a dictionary, and an exhaustive list of synonyms is given for each definition of every word. Clarifications such as "informal", "slang", "archaic", etc. are provided where appropriate. There are 1.5 million words in "The Synonym Finder", including variations on the same root word. That's more than 4 times the number of words in "Roget's International Thesaurus". If you simply want to find synonyms, this is the book for you. It isn't as versatile as a thesaurus that is organized by subject, but it's more to the point and easier to use if you are simply looking for word alternatives. Roget's is a better research tool, but this is a better and far more efficient synonym finder, and I think that students will prefer it to Roget's. My one pet peeve about the book is that the hardback edition doesn't have a dust jacket. The publisher may have thought a dust jacket would just be a nuisance on a reference book, but I would have preferred one for protection. I only wish "The Synonym Finder" were also available as software, as I have limited space for books within arm's reach of my computer. I use "The Synonym Finder" more frequently than my dictionary, Roget's Thesaurus, and Random House Word Menu combined. I think any writer will find it indispensable, and it would make great gift for middle school, high school, and college students.
