I highly recommend this book [he may have a new one out]. I got the following information and reviews from Amazon.com. I also think Outdoorsman's Edge Book club has the newest book available but they have revised their website and until I get a new membership number I can't check the availability of Trout's newest book on trailing wounded deer.

Trailing Whitetails
by John Trout
Publisher: North Country Press; ISBN: 0896211096; (January 1987)

Must reading for the serious whitetail hunter., November 23, 1998
This book is loaded with facts about whitetail behavior, in addition to addressing the serious questions a hunter asks him or herself after they fire a shot. It took me 35 years and forty-five deer to learn only half of the strategies for understanding deer reactions after the instant the trigger is squeezed. While a factual presentation, this book is easy and interesting to read. Makes an excellent and unusual gift to the advanced hunter who already knows the "basics".

Trailing Whitetails by John Trout Jr. is the best book on the topic of recovering wounded deer that I've come across. At my NYS Bowhunter Education classes I recommend it as a "must read" for all beginning bowhunters. I have given many copies away as gifts. After 30 years of bowhunting for whitetail deer I still find myself refering back to this important book.
