A terrible follow up to Sticker Graphics 1 . Don't get swindled by the packaging.  The graphical quality of the contents are suspect as a fair amount of the illustrations I can only describe as grade school crayon scribbles.  There are a few exceptions to the rule, but not enough to warrant purchase

Ex Output:
NEG


Ex Input:
A Must Have for the Mystery Connoisseur! . This is a wonderful tool to keep track of all those mystery books on your shelves. This book offers a comprehensive listing of women's fiction mysteries. Books are listed by author and title. It is great way to see the  order of books written in a series. There is also a check list where you  can check off the book once you purchase it, and then check it after you  read it. I like to make notations next to the books once I finish the book.  Books that have been nominated or received awards are designated with a  star by the title

Ex Output:
POS

A very difficult book to read. . Thsi book is for someone who has an extense knowledge of the Byzantine empire. I do not posses such knowledge and got lost inmediatly while trying to read this book. The author's style adapts for someone who knows all the history of the people involved in this empire already. I couldn't even finish the first chapter because I found myself asking: who is he talking about? every two  lines

Ex Output:

NEG
