True. Worried that someday that everything will collapse like
the books in "Time Machine" with some Eloi in the background
going "Duuuude!"?
There is some research on deacidification, EG
http://lcweb.loc.gov/preserv/rt/copper/cops_1.html
which I'm not up on. Sounds impractical in most cases.
The Lib.Congress entry on preserving newspaper goes on to mention
oddly "Digitization of Newspapers on Microfilm" (a contradiction?)

I'd agree that photographing the materials would be the best choice, and
digital would be best in terms of forward compatibility. A scanner would
be good for <8x10 articles, a 5+MPixel camera for whole pages of
newspaper. I'm getting interested in constructing a copystand for whole
sheets. A 5MPix would get the whole page at 125 dpi, something of a
minimum acceptable limit... with a scanner on cut articles its easier to
do, and at 300 dpi no less.
