Who Is That Man?: In Search of the Real Bob Dylan, by David Dalton, is marked down to
$1.99 at Amazon at the present moment. "In
Who Is That Man? David Dalton provides a new perspective on the man, the myth, and the musical era that forged them both." (from B&N).
I noticed that it is also a NOOK Daily Find; I don't know if Amazon's markdown is a price match kind of thing or an independent move on their part. The point being, if it is a price match, the price may not last past today.
