"Rainbow Quest does talk about the Chicago scene, but not in any great detail. "

Cohen's book covers a great deal of territory and it is too much to expect it to go into "great" detail. A book that covers so much detail would never find a publisher. I would catagorize Cohen's book as going into "good" detail about Chicago, Denver, New York, Los Angeles, Boston and more. It is meant to be an overview of the entire folk revival and I think it does more than an adequate job. I highly recommend it, as I would many of the other books mentioned.
