Well, you can start with the Wikipedia article on Digital Preservation. And then follow links around some. Or go ask your local archivist. Or find a librarian forum and ask there.

Seriously--they're the experts. And there are a lot of digital archives at colleges and such that are on a small enough scale that their solutions would be practical for individuals too.

Don't forget Peeps, which is my favorite Westerfeld.

Seriously, a lot of the best SF/F is being marketed in the YA section these days. I'd refer everyone to this thread at BoingBoing, which has a good overview of recent YA.

And everyone here at Slashdot who hasn't recommended Little Brother yet should be ashamed.
