Query: Another good survivalist related book to own

Like the title says, I only gave it 4 stars because I have not read through it. More or less it covers a variety of topics and so far very good. I figured it would be another good book to add to my library "When technology does fail". Basically most of the skills and techniques that are in it you can look up on the internet, but for me and probably others it's just nice to have all that knowledge gathered into this book. Not saying EVERYTHING is covered in this one book but, I would say it's a good starting point.
