Example Input: A Great book for the Early Childhood Classroom . This book helps you look at the big picture from beginning to end. Nature should exist in the classroom all year around. I love the open ended growing activities and setting up a growing center. I'm in the process of doing this in my classroom and the children love it. Check out their other books on structures and water too!
Example Output: POS

Example Input: Over 2000 entries . Blacklisted: The Film Lover's Guide To The Hollywood Blacklist is the collaboratively effort of Paul Buhle and Dave Wagner and an alphabetically arranged encyclopedia of entries concerning the films, directors, stars, writers, producers, designers, and others who suffered being blacklisted because of the House Un-American Activities Committee during their infamous Hollywood blacklist era. Over 2000 entries point the reader in the direction of grand works that were covered in shadow during a dangerous time in American history, including films such as &quot;Roman Holiday&quot; and &quot;Bridge on the River Kwai&quot;. Blacklisted is a welcome and greatly appreciated contribution to Cinematic Studies reference collections
Example Output: POS

Example Input: Not for the solo lawyer; not about marketing, except for the author . I was disappointed by this book.  I am a solo litigation attorney, and I read the book to get ideas on marketing.  It gave me some ideas.  Perhaps the most valuable idea was to focus more on customer service; Dahut has an interesting discussion about exactly what that means and how we can do it better.  By and large, however, this is a book by and for big firm attorneys.  It is about big firm angst and how it can be combated by hiring experts such as Dahut to do extensive consulting work for your firm.  Dahut does not acknowledge, and does not care, that most attorneys are solos or work in small firms, and that we have very different issues than agonizing over whether we have lost our soul by conforming to much to dead firm culture
Example Output:
NEG
