Route 66 map/book recomendations

i know a few here have driven the mother road. does anyone have recommendations on maps or book that will help me plan the trip and what to see.?
Route 66 Traveler's Guide by Tom Snyder ISBN-10:0-312-25417-2, is a must if you want to see ALL the original road. First half takes you east to west and the second half west to east. The most complete turn by turn manual I've ever seen.
