Wonder what CNN's web page looked on Sept. 11, 2001? What happens to old web pages? How are they preserved? Most people don't care to think about this. But, if you are an archivist, you do. I'm not. But I'm glad that some people are.
Check out InternetArchive.org and try the Way Back Machine. You can type in a web address and see what it was like 5, or even 10 years ago (if it existed back then). Pretty cool.
