The New Complete Book of Self-Sufficiency: The Classic Guide for Realists and Dreamers
Why this book?
This is the classic book on self-sufficiency that started my interest when I first read it decades ago. John Seymour was the master and teacher and the book is crammed with practical methods with many useful illustrations. Many people I know who are fascinated with the idea of self-sufficiency, and successful practitioners, were initially inspired by this book.
