Alex Jones
He can be over the top at times but he's very wired into current events. His unique take on events provides some valuable insight to some of the potential threats we face. His sites offer a wealth of free multimedia information.

Coast to Coast AM
Like Alex Jones, George Noory has a unique perspective. The first ten minutes of his show usually includes a roundup of news items that you may not see elsewhere for a while. Some of his radio talk show guests have presented authoritative information on important (at times critical) subjects long before the mass media embraces them.

CBS News Disaster Links
One of the most comprehensive site I've seen. Links to every conceivable site that is authoritative and related to the topic. The variety may overwhelm you.

Disaster Center
Like the CBS site, this provides a one-stop overview of the current situation, worldwide. The site is very graphic and (in the fashion of Bloomberg TV) provides "at a glance" continuously updated information.

Emergency Preparedness Dude - Very practical disaster prep and recovery information. I especially like his "Your Water Needs" calculator. Site is oriented toward natural disasters.

Military operational equipment and survival clothing
The largest manufacturer and retail distributor of military survival and operational clothing and equipment in Great Britain, with 6 outlets situated throughout the UK.

Radiation Survival
A wealth of information about surviving radiation emergencies.

Toxic Substances & Disease Registry Publications List
ATSDR is directed by congressional mandate to perform specific functions concerning the effect on public health of hazardous substances in the environment.

SurvivalistBoards
Extensive no-nonsense message board system. Many features including product ordering.

US Joint Services Manuals
An extremely comprehensive collection of field manuals and other military manuals - free downloads.
