A couple of things struck me while reading this. One, there needs to be some other media form for this kind of thing--READING about music just doesn't do it--you want to hear the examples. Two, while this is a good rundown of the folk scene in the 50s-60s, it really is unfinished. Even after the Coen brothers' film and this book, there's still room for a great fiction/non-fiction telling of this period, and room for another folk revival, too. Maybe Ken Burns might want to take this on the way he took on jazz.
To me the great value in reading this was a reminder of artists I had forgotten about years ago, and the discovery of names I wasn't ever aware of. And thanks to the internet, I'm discovering the music all over again.
