I did do a search of several combinations of the words Bob, Dylan, Chronicles, Autobiography, Book, using upper & lower case. I turned up several threads, but none concerning the book.
I listen to the radio, I read newpapers, I watch TV, I talk to people with similar interests, I just can't believe that an event of such gravity can not only slip past me, but remain unknown for so long.
I think it's spooky.
