In response to the previous post: I would not feel alarmed about the missing information. I am certain hundreds of people were contributing to book. An omission in the history department would not likely affect other sections. One book will never be able to capture everything considered "essential". Essential for an American is not essential for, say, a European. No single book will make you "essentially informed".
I found the depth of this knowledge to be just right, though. I don't care to shine on Jeopardy. My goal is to become aware without getting too deeply into it unless I am really passionate about a particular subject.
Sure, some stuff is missing, but, what is there is PLENTY. For example: we all heard about Sunni and Shiites Islaam, but I doubt many, including, and especially, George Bush know the difference. How many of Seven Wonders of the World can you name? Do you know who Pygmalion was? Did you know television was invented in 1927? Did you know that America has the highest rate of STD's of all industrial nations? Do you know why? Do you care? If the examples did not evoke some sort of curiosity, this book, in all likelihood, will seem useless to you. But if you found that your brain lit up with tingly wonder, this book would probably be a good place to start.
On the negative side, truthfully, there is nothing unique or incredible about this book that sets it apart from others, maybe a little heavier. It's just like any other almanacs published every year by New York Times. It's just another information-filled book, not better or worse....
This book has over 1300 pages without a single illustration, and of course, is basic, but don't let it fool you, you can still find something new that can send you to the library or the web to satisfy your curiosity. If you are an average American, (not a geek, who probably already knows all this stuff anyway), if you are curious about the world you live in, and would like not to appear dumb when others discuss world's events at a party, you will surely find something fascinating about this "everyday" stuff. Something you probably had heard mentioned as recently as today without really realizing how little you knew about the subject in point. Each category contains 10-15 pages. Topics: Philosophy, Psychology, Broadway, Geology, Geography, Earth Science, History, World Wars, Music, Political Science, pop culture, world events and so on...
