How many times can you call a collection of political essays a page turner? Well, how many Howard Zinn books are there?
This is a really comprehensive collection of Zinn's work, and makes a nice compliment to his quintessential "People's History of the US." It picks up on the same subject matter, but in Zinn's voice as an observer to the great political struggles of this century. It is, of course, typical, liberal, activist-minded Zinn, but I view this as a good thing -- he has a great deal of perspective as both an academic and an activist.
As for my favorite parts...I was interested and impressed to read of Zinn's activism during the Civil Rights Movement. This is a great first-hand account from someone who was along for the ride. I also enjoy his discussion of pacifism in the context of WWII, which is a difficult and delicate subject to tackle. I respect that he attempts to explain his anti-war beliefs with respect to this "good war."
I have found this book useful in very practical ways as well. I used some essays as texts in the activist internship class I taught, and I also referenced the list of important and influential books Zinn includes in an appendix.
