There's no better alternative. I mean who drags out an encyclopedia nowadays? It wouldn't even surprise me if a scandal appeared where a now underfunded encyclopedia had staff copying from Wikipedia for it's books. Before the true and total death of encyclopedias I probably should go out and buy one...

Edit: oh God I'm old. Regular encyclopedias are online now. https://en.m.wikipedia.org/wiki/List_of_online_encyclopedias
