Printed References

Some times you just have to do the calculating yourself. But you can get a leg up if you have printed information at your fingertips. A pencil, paper, maybe a slide rule, and a pocket reference was, once, all one needed.

I wonder how much information now exists only in "e" form - magnetic tape/disk, optical media, silicon... Ink on paper can last thousands of years. Can the same be said of digital data? Can it be said of the technology needed to read digital data? And just how precariously are we perched on technology's ever narrowing tip?
