Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Published in 2004, six years ago

This is just a note about this title, which would seem to be useful and encouraging based on reviews, title, and promo. So much has changed in these six years that no newer edition makes the book info suspicious to me. I always tell writiing students in college to use the newest and latest sources for research. Why shouldn't this apply? Perhaps another reviewer can address this issue, the rapidly changing book market and tone of our nation, etc., that would not be addressed in a book published in 2004.
