After all, when you’re talking about survival guides it seems odd to omit classics like The Zombie Survival Guide (now in flashcard form!). And I still have to somehow acquire How To Survive a Robot Uprising. Wilson’s Where’s My Jetpack? looks fun, too.
Finishing up, I heartily recommend Pocket Guide To The Apocalypse: The Official Field Manual For The End Of The World: it’s not really a field manual, but it does have the singular virtue of containing a general analysis of the various threads of Western eschatological thinking by somebody who doesn’t hate evangelical Christians. So I guess that it is a field manual, only not for the stated purpose.
[UPDATE] I have been properly dinged for not including How to Build a Robot Army: Tips on Defending Planet Earth Against Alien Invaders, Ninjas, and Zombies; let me head off future criticisms at the pass by also including How to Rule the World: A Handbook for the Aspiring Dictator and How to Be a Villain: Evil Laughs, Secret Lairs, Master Plans, and More!!!. These kinds of books have pretty long subtitles, huh?
