True....

Well, in the 1890'~s, acid paper had started to be used, right?

True -- the problem of acid paper has received attention, and acid free
paper is once again being used, at least for high-quality books.
 
So future archaeologists may then conclude that book printing ceased
around 1880, but was again resumed around 2000....

Anyway, I merely  wanted to point out that storing data such that
it remains accessible for a very long time is problematic.  NASA
had a project some 5-10 years ago of trnasferring its old spacecraft
data from obsolete tape formats to CD-ROM's.  Their #1 problem was
finding equipment which was able to read those obsolete tapes -- but
once they succeeded in doing that, problem #2 popper up: these tapes
would quite often break when played back....
 
 
Data storage over long periods of time indeed has its problems.  But
I don't think CD's spontaneously disintegrating will be the main
problpem.  A more severe problem will probably be CD-ROM's becoming
an obsolete data storeage medium, i.e. in 10-15 years or so it may
become difficult to find a CD-ROM reader.
