Books
The Foxfire Book series (in 11 volumes, but the first five are the best)
When Technology Fails: A Manual for Self-Reliance, Sustainability, and Surviving the Long Emergency by Matthew Stein (SurvivalBlog’s Backcountry Editor)
Fiction
Some Will Not Die by Algis Budrys (Plague total wipe-out scenario. This book was another with an influence in my writing.)
Movies
Raiders of the Lost Ark (The later installments in the Indiana Jones movies aren’t nearly as good.)
