Hard to take at one sitting. Author seems upset that his reading of history isn't taught in textbooks. There can be different interpretations of events, and not all events can be put in a single textbook. Author's argument, I suppose, is that most textbooks' information is so insipid or wrong (e.g. Thanksgiving, Helen Keller) that it's counterproductive to have it in there.
I suppose if you are a scholar and like 20-30 footnotes per page, you will enjoy this tome. I found wading through 40 pages substantiating Columbus' non-discovery of America about as exciting as reading the nemes of all the Joneses in a telephone directory. Each name is the same with a few variations and different addresses.
Interestingly, the book provides nothing of the author's credentials except two lines on the back cover, which state that he is a professor emeritous in socialogy from the University of New Hampshire. Not much in the way of credentials to support his views.
The writing is pedantic and boring. I think from the title, the subject matter could have come to life with some colorful, yet factual, writing. It might also have been more interesting if it were about 200 pages shorter than it is. On the other hand, if you are an insomniac, this book should be a great aid to you. And if you are a true scholar, which I admittedly am not, have at it. For those who are not true scholers, you might consider taking it off your wish list.
