No accidental source code as far as I know, but if they're collecting magazine CDs in general I have a bunch of mid-90s cover CDs which I'd be happy to rip. (Sadly not the one coverdisc I'd really love to be reunited with, though it must be in my parents' attic somewhere...)

Is there a guide to the best way to rip the disc image, preferred formats for inlay scans, etc?

And do I need to do anything regarding copyright? I would definitely not want to cause any legal trouble for archive.org as it is a v valuable resource.
