Query: Skip this book unless you love words and have much time to waste

This book has an enormous number of synonyms and antonyms. The problem is that the index is so tiny, it is rare you will find in it the word you want, or even one near to it. So you go on a hunt. Take the word "primacy". The nearest word in the index is "prime". But this is in the section on preparedness. So perhaps "primary", but this is not in the index. Try perhaps "first". There is much there, but nothing near "primary", and with no assurance that "primacy" will be anywhere nearby. By now you have read hundreds of words and are nowhere near the word you set out to find. I rarely find anything I'm looking for in this book. My advice is find an indexed thesaurus that has a large index. This one is only 43 pages long in a book over 900 pages.
