If you haven’t already discovered the Wikipedia then you should, if you at all like encyclopedias. And even if you dislike wikis it’s alright, there’s proper search and navigation elements, and enough content there already to be quite useful so that one need not feel guilty for not contributing.
Surfing it reminds me of when I was young and visiting a friend who had a set of encyclopedias, lying on the floor on rainy afternoons, paging through them.
Here’s a telling excerpt from the Creative destruction page:
Most economists agree that long-term economic growth is largely the product of technological innovation. Thus, some see it as a scandal that Schumpeter is absent from many 600 page elementary economic texts’ indexes. Schumpeter’s solution would be for a new generation of textbooks to emerge, which students would choose, in partial defiance of their lecturers. Wikipedia is now one of those texts!
