A lot of lot of knowledge fits on a bank card size nanofiche. You make ten thousand of them, and people put them away as best as they can. Some will melt in a fire, or get blasted apart, some will be burried and forgotten forever. But some will be more lucky, by just chance they will end up in an atick or crawlspace where nobody disturbs them. Not counting that we can hide some of them in places where they are unlikely to be disturbed, such as place a few on the moon or place a copy on every single geo and lagrange point destined satelite. Heck, burry a few on a glacier and they will naturally re-appear in a few thousand years.
