From what I have heard, Zinn’s dubious lightweight book has not a single footnote, attribution, or even a bibliography. I wonder if this is true? If so, it is a joke, a dangerously misleading and ignorance invoking one at that. The “teacher”, if that is her photo, is a child, and based on her intellectual laziness with her textbook choice, an airhead.
It is true, but he does have sources cited in text. The problem (besides no page numbers, editions, etc) is HOW he uses the sources. He uses ellipses to remove material unsupportive of his birws; he’s terribly selective.
You can read Grabar’s book or go to my site www.wildworldofhistory.com on the VIP side where I have a series of lessons called “The Horrible History of Howard Zinn”.
