Query: Advanced Word Processing

After twenty-seven years of machine processing of words -- I certainly don't need a book to regurgitate the basics. This one does just that -- of course -- but it also has the best coverage of all the advanced feastures -- such as references, indexing, collaboration, etc. No computer reference book survives for more than a year or two -- a book needs to be outstanding to be worth the investment. This one is worth it.
