Example Input: Questioning what really drives the future... . I just had the pleasure of reading an advance copy of John Naisbitt's Mind Set!: Reset Your Thinking and See the Future.  There's a lot in this book that I'd like to recommend for those who think everything is "the next big thing"...  It's really not.    Contents:   Part 1 - Mindsets: Most Things Remain Constant; The Future Is Embedded In The Present; Focus On The Score Of The Game; Understand How Powerful It Is Not To Have To Be Right; See The Future As A Picture Puzzle; Don't Get So Far Ahead Of The Parade That They Don't Know You Are In It; Resistance To Change Falls For Benefits; Things That We Expect To Happen Always Happen More Slowly; You Don't Get Results By Solving Problems, But By Exploiting Opportunities; Don't Add Unless You Subtract; Consider The Ecology Of Technology  Part 2 - Pictures Of The Future: Culture - A Visual Culture Is Taking Over The World; Economics - From Nation-State To Economic Domains; China - Will The Dragon Devour Us Or Will It Be The Dragon We Ride?; Europe - Metamorphosis To History Theme Park; Our Evolutionary Era - No Next Big Thing  End Notes; Index    Naisbitt, the author of Megatrends, came up with a number of mindsets that can help someone understand where things are going in the future.  From that initial list, he pared down the items until he came up with what he felt are the most important eleven items that matter.  These mindsets, if understood, directly affect how you view current events and interpret your surroundings.  For instance, it's easy to look at each new technology and think that it will change everything.  But in reality, the same underlying forces continue to drive people's lives.  Business is in a constant state of flux, but it still ends up being all about buying and selling.  In sports, the one-handed jump shot in basketball completely changed the look of the game in 1936, but the game itself was still the same...  score a basket.  Once you strip away the fluff and hype, it's easier to understand where the general flow of life is going.  Or my favorite...  don't add something unless you subtract something.  Setting a cap on a situation (be it a sports roster or a number of menu items in a restaurant) forces you to weigh the merits of each item, keeping only the things that return value and dropping items that no longer measure up to the others.  Something to remember before you make yet another commitment...    Part 2 of the book applies a number of these mindsets to different current events and situations.  Personally, I found this part of the book a bit more unfocused than the first.  While I understand that the visual is becoming more important in today's society, I had a hard time staying focused on where the chapter was going.  He does tie the mindsets into the conclusions he draws, but I found the mindsets themselves to be more personally useful for my own life.    Definitely worth reading, even if you don't necessarily agree with him on how the mindsets play out.  I'll be revisiting the mindsets a number of times to get them firmly embedded in my brain.  And don't be surprised if I turn down some "adds" because I'm not ready to "subtract" something..

Example Input: NYT "Top 50" list . This book is phenomenally crafted, written with heart and sincerity.   I cannot recommend it strongly enough.  I learned about it through the recent New York Times "top fifty" recommended list, which included several authors I'd never heard of.   Frankly I was concerned that the list would have a couple of weak entries as happens.  "Independence Day" reaffirms my faith in reviews, polls, awards (Pulizer) and I'm glad to know that this is just the second installment of an iconic series.    To say the language "Independence Day" is poetic is an understatement.  Ford exercises control over both the vernacular and the estoric (on average I didn't know a word every five pages, but that's a good thing - the language is rich and sincere as is the engrossing narrative).  The word "Angstrom" appears in the book, perhaps a footnote to Updike, who knows?    Frank's sale to the Markhams is one of those protracted dramas, no, comedies, that weaves through like a Wagner liefmotif.   Wait, that simile strikes the wrong key, because the Markhams, as you get to know them, and you will, in richly parenthetical passages, represent everything you the reader and Frank dislike about pure unadulterated dumbasses.    Ok, I can go on and on about this book, it's subtleties, it's heartwrenching passages about love and divorce, but no, go read it
Example Output: POS

Example Input: Flashy book with little actual theoretical/critical content . I would like to think of myself as someone who is fairly well informed of the (short) history and theory of video art. As such, I will say this book is a very basic, sort of bland overview of the langauge of video. It's very well put together in terms of it being flashy and "hip"; all the stills are well printed and all the big, "in-vogue" art star names are included (but where are people like Haron Faroqi? Or did he just shoot on film and thus not make the hipster cut?) With that said, there is little to no actual critical content in the writing. It introduces concepts in a very simple way, and doesn't actually end up saying much other than varying degrees of further artist canonization. I don't know maybe I am just too picky and also semi-brainwashed by more rigorous academic books on the topic, but I actually stopped reading the book because it was so boring. If you're looking for a slick coffee table book with which to impress your friends, one that will let them know that you too have joined that cool club called "connoisseurship of video art" and a book that they will tend to thumb through just to look at "all the pretty pictures" (which I find hilariously absurd- a book of still images taken from video), then this book is for you. If you're looking for anything deeper than that, I would look elsewhere to titles like "Illuminating Video : An Essential Guide to Video Art" by David Ross, Doug Hall, Sally Jo Fifer, and David Bolt.
