Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Not as advertised. Get the Penguin edition!

First of all,, this is not the complete volume - not even close. And it doesnt even say 'abridged edition' or anything. amazon was cool about it though and refunded me and let me keep the book (even though it sucks, still a nice gesture). Second, it's poorly edited with many typos.
