Back in the dark times before the internet, you generally had to look specific things up in books. Really, you had to kind of stumble across them because you couldn't count always count on books to have the info exactly where you needed it, when you needed it.
Now the internet's dark times are related more to the various comments sections. The bright times are random, unexpected, unusual facts. The thing that hasn't changed is that you can still stumble on them. But you can look them up much easier now, so you have that going for you, which is nice.
