Umm ... DEC's paperbacks.
And putting on the wayback machine, this is what Doug Jones was
doing in the previous millenium to preserve the early (60's) DEC paperbacks.
I'm not
sure what the paper of choice for databooks is, generally if a
book uses sized bond paper it's not at highest risk, but for the most
part wood paper made before the '80s will have some degree of risk (and
more modern papers that are not acid-free archival grade).
So can anything be done for them?
Absolutely. Cut off the binding and scan. Or if you insist on not doing
that, then follow the procedure which Al mentions by reference as
have several others of us here previously in this thread and previously
in similar threads that appear several times a year.

I've done it in classes taught and led and supervised by professionals :-).
That doesn't make me a pro!
