Ben Macintyre of the Times online has written a piece on archiving digital information in History 1980-2000 has disappeared into the ether. Sorry

The digital age brought with it the false promise that everything written, filmed, photographed or recorded might now be preserved, for ever. The “save” key would eliminate the need for filing and storage. Since 1945 we have gathered 100 times more information than in the whole of human history up until that point. Entire libraries could be preserved on disks that fitted into a pocket. Paper was dead.

It has not quite worked out that way. Digital information may be impossibly voluminous and convenient, but it is also vulnerable and dangerously disposable. Already a vast amount of information has been lost. CDs disintegrate in just 20 years, whereas the Domesday Book, written on sheepskin in 1086, will still be with us in another millennium. Few people still write regular letters, but their replacement, the ubiquitous e-mail, is so easily deleted and forgotten, to say nothing of the fleeting text message.
