The internet isn't quite the all-encompassing fount of knowledge that it's sometimes made out to be.
I often do amateur research on local history and there are lots of locally significant places and events which have few or no results on the open internet. You have to manually trawl through newspaper archives etc to get any solid info and these may be missing numbers or locked behind a paywall.
If you are lucky enough to speak to someone who remembers events some time ago, it's clear that there are vast areas of human experience that no one has written up or recorded online.
