Example Input: Some textbook! . This is the longest textbook I have in my collection and it is also a bad investment book at that. I know some readers really enjoyed the detailed explanations, but the book was too detailed and wordy for me. Many of the explanations are unnecessary and examples can be simplified to get to the core of the problem/concept and drive at a much stronger intuitive understanding. But this book doesn't do that. It is cluttered with definitions and wordiness that kill the intuition one could get by reading a more concise, straightforward text. A really good book is Investment Science, by David Luenberger. Although his text assumes you have some background in calc/stat/probability theory, the writing, examples, and organization is far superior. You'll actually begin to understand how investment really works, without getting bogged down by the numbers, terminology, and jargon
Example Output: NEG

Example Input: A fun take on an old song . Watch out, this book is addictive.  My 14 month old daughter insists that we read it when ever she sees the book.  The book provides a fun take off on the traditional song.  The illustrations are also amusing.  Just be  ready to sing the song over and over and...
Example Output: POS

Example Input: Be Prepared for an Eye Opener . Even a few years after it's release, Eric Schlosser's "Fast Food Nation" still sends a strong message to the reader and exposes the fast food industry for what it really is... a group of very large and very powerful marketing companies... not a purveyor of good food--or nutritious food for that matter.     For many years, food additives and techniques have been the dirty little secret of the industry, but not these things are starting to surface.    The book takes you through the processing warehouses and chemical plants that the industry uses to "make" the foods served at these restaurants.  It opens your eyes to practices done to cut costs and sacrifice your health in the process.    I've recommended this book to many of my clients and many are reluctant to read it at all, probably because of the emotional attachment they have to their favorite fast food.    Since this book came out, there are so many more studies and reports on what is in the fast foods then there ever were before.  Reports including additives, trans-fats and other inflammation causing ingredients are helping the industry clean up it's act.    This doesn't mean that fast food is good for you, it just means that Schlosser has done an excellent job at bringing attention to an industry that wasn't challenged as strongly as it should have been.    I personally haven't had fast food for over 5 years, but--even that far removed--as I was reading this I felt sick to my stomach.    Read this book and you'll never step foot in McDonalds again.
