I have some reservations about an American (or a state) organisation being in charge of archiving the Internet and other media, but—
I wanted to buy-up shareware CDs and go through and archive them, but kinda forgot about it. This was also partly a plan to hunt for some shareware I vaguely remember that I'd like to find again.
An archive of websites. Unfortunately they're often incomplete, especially things like images and downloads are missing, but it's still very useful.
