Ex Input:
Definitive...a wonderful addition to my library . I purchased this book when it first came out.  I thoroughly enjoyed it at that time, and have used it as a reference ever since.  What so many do not realize is that different treatments (distillation vs. tincture vs. absolute vs. hydrosol, etc.) of a plant result in often VERY different properties comprising that substance.  So finally having some insights into the properties of hydrosols, the water remaining from the distillation of a plant, is/was much needed.  No other work like it had been available.    And what a revelation about many of them.  Most people, even those working with essential oils and their cousins were not aware of what this or that hydrosol might do, let alone how to get their hands on it.    Really needed and really wonderful work

Ex Output:
POS

Wish I had known... . I don't care how great this book would have turned out to be if I had finished it.  Within the first 30 pages, Stephanie recalls the sex she had with the guy she's hunting down when she was 6 and he was 8 years old; and her Grandpa Plum shooting a grossly neglected family pet to end the animal's pain and suffering. If I had known about the distasteful elements in this book, I would never have purchased it

Ex Output:
NEG


Ex Input:
The Civil WAR . Mr Foote has written about the "War Between the States".  He tells the story of the WAR.  It is not the story of slavery or its demise, not about the country's explosive economic growth that ensued, not about a lot of other subjects, just about the WAR and the men who led it and fought it.    If you want to experience the ghastlyness that millions of Americans did in 1862 to 1865, read these books.  No one has done this better.
