Read it.. They had it in my junior high school library, along with a few other SHTF-type books. Looking back, I think the librarian was a closet survivalist
ETA- there was an interesting series of books for young readers titled "After the Bomb". Reading level was pretty basic and there wasn't an overage of useful info, but it piqued an interest.
There was another book whose title I can't remember.. The first half was a fictional account of a group surviving nukes in California that read like a "how-to" handbook. The second half was strictly "how to", including a design for a home brew radiometer. It was a straight trade paperback, but I'd love to find out what it was and find another copy.
ETA2- It was "Pulling Through" by Dean Ing. Just found it on amazon. Fantastic book.
