Here are some excellent books on the subject:
"Finding Your Way In The Outdoors", Mooers
"The Wilderness Route Finder", Rutstrum
"Land Navigation Handbook", Kals
"Wilderness Navigation", Burns & Burns
"Compass & Map Navigator", Hodgson
"Be Expert With Map & Compass", Kjellstrom
All are fine books with the last four being of more recent vintage and pretty easy for the novice to follow and learn from.
