As some of you may or may not know if you link to the NY Times, after a little while that article gets locked behind the Times’ archive and you have to pay to get access to it. Now I am not against making some money, but this gives links an expiration date (why pay when you can go to your library and use mircofiche and see what you need to see).
Anyway, the NY Times entered into a partnership with Userland, which in part, allows you to link with confidence. Any link that is formatted correctly will be not expire, the story will be freely available. I have know about this for some time, but I could never remember the required format. Thanks to Aaron I no longer need to!
The New York Times Link Generator takes any URL from the NY Times, and well generates a link that will last forever.
