Levels of Knowledge

I am preparing for a lecture next week, and I wonder if you all could help me with my data gathering. I am looking for a good statistic on increases in level of knowledge since:

1. The invention of Gutenberg's printing press
2. The publication of "The Origin of the Species"
3. The invention of the computer
4. The commercialization of the Internet (1992)

I am sure that data is out there somewhere, but I have had a hard time finding it. So, I turned to the wisdom of the crowds. Any help you can give would be appreciated.

Just curious what you mean by "levels of knowledge" here. Information access is a better way to look at it and something that has been measured. I would look at Levinson's book The Soft Edge for some good data in that regard.

will, Alvin Toffler's Book, Future Shock has some great info on the rate of change and how society is affected. In it, he talks about..I'll just call you.
