"Whitetail- Fundamentals and Fine Points for the Hunter" George Mattis
"The Deer Hunter's Guide" Francis E. Sell
Those two give a good perspective on whitetails in the north-central U.S. and blacktails respectively, with great stuff on still-hunting and trail-watching.
"The Life of the Hunt" by some guy named Barnett or Boswell, or something like that.
About half-way through that one I started limited myself to a chapter a day or so because I didn't want it to end.
