Imagine the following.
You are home all day, sick from work. You don't go anywhere special, or do anything outside your home. Yet, at the end of the day, you look down at your hand and to your horror, discover that your wedding ring has slipped off your finger sometime during the day! Eek!
Well, it's not quite that dire. I didn't lose my wedding ring.
My wife did.
They say that lost items are always in the last place you look. So, the question is: where is the last place you would look for a missing ring?
The National Endowment for the Humanities is teaming with the Library of Congress to make 30 million newpaper pages from 1836 to 1922 available for free download over the net.
The span of the joint project is limited because type faces of printers used before 1836 are too difficult for optical scanners to read, and copyright restrictions are in force on papers published after 1923.
Cory Doctorow mentioned Ralph Koster's Theory of Fun, an as yet unreleased (?) book on the design of games. Ralph has prepared 50 page PDF file which describes some of its content. Good stuff.
