Wrong. It still takes a long time - of the order of minutes per A4 page (5-10KB of data, now we have TBs of data to archive and restore), even with OCR and ECC technologies, which didn't really exist back in the 1980s. > 2.

Quite true, but the cost of curating the data (particularly when the curating gets it wrong) typically outweighs the cost of storing the data and transferring the data to new digital formats when they arise by many orders of magnitude. BTW - I do curate my own data, mainly because too much cruft makes me inefficient, but I don't dare curate my wife's data. So I have to put up with the cruft whenever she asks me to find XXX. > 3.

Literally, audio is ephemeral. To store it requires a storage medium, whether they be wax cylinders, or modern MP3 data files on flash media. > 5-1000 think about alll the rest what we do not even think of today We have to think about it today, otherwise it is lost tomorrow. > > John Mikes > > > On Mon, Feb 3, 2014 at 4:09 PM, Russell Standish <li...@hpcoders.com.au>wrote: > > > On Mon, Feb 03, 2014 at 03:45:43PM -0500, John Mikes wrote: > > > Russell wrote Jan 26: > > > > > > .*.We must make sure we have backups this time!*. > > > > > > How about on paper?
