Inspired by the post about the hieroglyphs the one dude hoped would last forever.
People always talk about future historians being confused at memes and old forums, but surely a lot of catastrophic events could just wipe out the internet wholesale, right? If something REALLY COOL 
like a giant meteor wiped out everybody, what if aliens came along and were deeply confused that our culture seems to end randomly in the mid 2010s, subsumed by an internet whose only remaining shreds are references in big scientific studies?
The history textbooks on our dumb asses would surely read "and the humans all talked into screens and used "hyper links" to share information and opinions. Very little is known about this obscure human ritual as no evidence can be found of its existence beyond scattered references in ancient texts contemporary to its existence."
Thinkin bout the impermanence of the internet rn
It really depends on the paper. Like you can get "archival" paper that has low lignen levels and won't yellow and deteriorate as fast. At the other end you have like newsprint and cheap paperbacks (the pulp in pulp fiction refers to the low quality of the paper in the books) and they really don't last. In general though, I think most of the old texts we have as books are written on parchment, which is leather. I do think there are ways to preserve paper, but it probably involves periodic maintenance and replacement and specific conditions.
Yeah only the modern paper that advertises itself as archival can last as long as a normal sheet of paper could a few hundred years ago. Also the parchment thing. And papyrus.
