*Agree*, in spades. As someone who used to be paid for being besotted with computers, I can say with the authority of bitter experience that hard copy is vastly superior for long-term storage .... as long as there's a sufficiently comprehensive index, or you're only interested in linear access. I'll curtail the coredump there, before I start wittering on about the Mark One Eyeball, or our library suffers gravitational collapse. Oook.
