I found Deep Survival a very worthwhile read and I will plan to acquire Will To Live - Stroud is the only half way rational TV personality.

For me at least, the classic survival text is "The Survival Book," by Paul H. Nesbitt, Alonzo W. Pond, and William H. Allen,published in 1959. I obtained it the year it was published, also the year I graduated from college, and really started to spend serious time outdoors.

Although it is obviously dated (no mention of GPS or cell phones!) it sets forth principles which remain valid today. Some quotes -

"This book as only one purpose - to aid and insure your survival after emergency aircraft landings regardless of geographic location."

"...the obstacles to be overcome [in survival] are not so much physical as mental" "...tools and training are not enough; none is effective without the will to survive."

The authors provide a lot of data and episodes from WWII which are quite informative. Rather quaint is what today would be considered overuse of the masculine pronoun. Many pf the first aid protocols are obsolete, like back pressure-arm lift artificial respiration. I still turn to my well thumbed copy because a lot of the book is simply timeless and always relevant.

You can actually find a copy on Amazon, and quite cheap, at that.
