A combination of the words Archivist and Survivalist.

Used to denote someone who hordes information that may help in any random situation, much like a survivalist makes preparations for widespread catastrophe.
Person A: Why do you have e-books on Lockpicking, Herbal remedies, Helicopter Piloting and 1000 other random subjects?

Person B: I'm an archivalist....I can't help it.
