Just to avoid any form of confusion, I define survival as "the skills necessary for surviving, primarily in wilderness settings", which sounds a bit trite, but is my way of pointing out that my opinion of the so called "survivalism" is rather poor. If you want to play soldiers, then you should take up Paint-ball or join the National Guard, Foreign Legion, Imperial Space Marines, or whatever is local and feels right for you. Wilderness survival is not about preparing for the end of civilization, building bunkers, or carrying enough guns to make seriously overload a Mac truck.
Actually, most of the brief information I have on the net on this topic right now is collected in the Frequently Asked Questions list that I maintain for the Primitive Skills Group. The PSG is a mailing-list for people who feel that a spending a weekend improving your skills with bowdrill fires is at least as worthwhile as spending it on the beach.
Actually, I am also a member of the Svenska Överlevnadsällskapet (Swedish Survival Guild).
Lately my interests have been more and more towards "stone age" survival, i.e. how to survive with no other equipment than was available during the stone age. I include in this the skills needed to make the equipment used at that time. The real biggie that I don't know much about is knapping rocks. Slate I can work, and the "barely walking upright" smach-rock-use-the-sharp-pieces stuff. One reason for this is the lack of suitable rocks in the area where I live. During the stone age flint was imported from Scania.
One more thing I do is to braintan deerhides. I've written some instructions on how you can make your own "indian" buckskin.
I have put a list of good books that might be of interest.
