Umm ... DEC's 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?
One thing you can do is store the books in tightly sealed plastic
bags - the browning on the paper is caused by oxygen in the air...the
pages are actually oxidizing slooooowwwwllllly (very slow fire).
Check with your local public library for suggestions on how to
protect old paper - you can make a base solution mixture for misting
the pages to neutralize the remaining acid in the paper.
