With new content created every split second and the ability to copy everything online in an instant, does copyright mean anything anymore? To those who use Creative Commons, it does.
The Wayback Machine at the Internet Archive collects copies of online materials - billions (85) of Web pages - and keeps them neatly archived by year and month. This is a grand resource for many purposes - not the least of which is to revive "dead" links. The Internet Archive also will serve up audio for podcasts and other applications!
