Worth a look. Lots of good info.

Quote from the site:

"Perhaps one of the most common misconceptions among Americans is that if a major wide-scale nuclear, biological or chemical disaster strikes, chances of survival would be extremely low. In reality, however, this couldn't be further from the truth. Many will survive, and most will not be prepared."

And perhaps the best aspect of the website:

The Journal of Civil Defense (JCD) is the official quarterly publication of The American Civil Defense Association (TACDA). The JCD presents information about the current threats that we face as American citizens, and provides practical solution-based content that helps equip and empower its readers with the knowledge and skills needed in order to be prepared should they be faced with a large-scale emergency or disaster.

We have made available, to our members for download, an archive of every past issue of the Journal of Civil Defense, spanning from 1968 up through the present. These archives are provided in PDF format, and require Adobe Reader to view.
