severe problem.

It isn't news to librarians or archivists, though. They know that media need to be rewritten every N years, where N depends on the medium. I assume that the Internet Archive, the CBI and the CHM are on top of this. Of course that won't help when our civilisation collapses. Clay tablets seem to be best for that.

(Even 30 years ago, CERN knew that the principal medium for archiving experimental raw data - mag tape - had a very finite lifetime and needed to be rewound every year or two and rewritten to a new tape after N years; I 
don't remember the value of N but I think it was probably 10. The rewinds 
were to mitigate magnetic print-through from one layer of tape to the next.)

So far I have lived through:  library catalogs on cards, microfilm, microfiche, punched cards, computer tapes (both 7 and 9 track), floppy disks, small and large hard disks, thumb drives, information servers, the web, and the cloud 
(and probably a few I’ve forgotten).  Each has had more or less a 
10 year time frame, before we moved on to something else and obsoleted everything that came before.  And try to find something that stands still on the web - now you see it, now you don’t. True, all these processes are faster and more portable, but not necessarily more durable. I say, historians should not count paper out, until they have something that can outlast it.

the math library. It has a glorious reading room with those great ?working and learning? murals of the early 20thC and they are making sure that they preserve and repair the glass floors of the stacks!! (Only have to light every other row on two floors.) The building and the math dept deserve each other. The floor plan has half floors and other twists and turns that make it almost a maze, and the secreted Bourbaki?s office!  ;-)

because the material has been scanned the original artifacts are no longer needed and can be discarded. It is far more important than that. At best, it means the artifacts don?t need to be handled as often, which as the 
centuries go on becomes more and more critical.

Archives with tight budgets employing people not used to engineering level salaries and other compensation tend to see scanning/digitizing as *very*, perhaps prohibitively, expensively.  Document contributors on this list might be able to help them think about digitizing costs and methods.

I have spent considerable time in archives across Asia and Europe and with private collectors. My experience goes well beyond computer museums, as I told Dave off-list, including junk rooms in the Vatican. (Sometimes one finds things in 
the oddest places.) ;-)
