And they are much easier to use. Instead of having to search though 100s of pages, you can just type in what you want and be taken right to it.
I'm sure you're just trying to make people laugh in a good way right?
Before the Internet their were these things called books, now not all of them, but some of them including reference guides had at the back of the book something called an index, like a search engine, you could thing of a phrase or what ever you were thinking of looking up, find the relevant page(s) and then find the information - saying that though, I've got no idea if the Chronology has an index and the first version of the Encyclopaedia doesn't. Plus I personally like to flick through a book for what I am looking for as sometimes you find something unexpected and learn something new.
Oh and isn't Memory Alpha and Beta like all Wiki's user created and any Tom, Dick or Harry can upload information and thus cause problems with the authenticity of the information.
Anyhow, my personal approach is to either look on a Wiki first and then, either a hard copy or another website to see if all sources match or vis versa.
