There are several sources for preppers and survivalists to glean important information.
You can always search Google and YouTube for a particular survival skill or how-to video. You can purchase preparedness guides on Amazon or at your local bookstore.
But arguably, one of the best resources for info (besides the Survival Bell site–heh!) is Survivalist magazine.
But before today, the only way to get the latest issue was at your local newsstand or a subscription delivery.
Well not anymore. All back issues, including out of print back issues, are now available digitally.
