Darwin's Library

They have digitized Charles Darwin's library and put it online for anyone to use.

Better than that - they have transcribed his annotations and marks in the books. That is cool because it gives you a sense of knowing how they read things.

I think I could get lost there. There's also another great time-wasting intellectual site like this, and that's the Leo Strauss Audio archive of his seminars. Open Courses before there were Open Courses.

Good luck being productive today! Aren't you glad you came here?
