"The Democracy of Learning" (Chapter 3 of "The Beginning and the End") is a short essay that appeared in "Know" magazine, which was a short-lived magazine that was put out by the makers of the "Encyclopaedia Britannica". It's ironic that Asimov was writing for the "Encyclopaedia Britannica" when he wrote:
And I look forward to the time when computerization will place in every home a terminal connected to some central library which will place, in facsimile, or on the television screen, the resources of human generations at the very fingertips of even the least of humanity. But that, alas, was not in my time.Well, Asimov, you're right. Wikipedia is incredible, and I'm sorry you missed it.
