And since the top of the thread is getting a lot of eyes, I'll reiterate the above, that 100% capture and preservation is not what librarians and archivists have all been wanting when they've made these observations.
Ephemerality can be good! Some things should come and go.
But the idea that things are online so they're stable and permanent and LESS volatile than a book has been... a real bane for a lot of us.
In some ways, maybe it's fine, but also maybe it's not. However the broadsides and pamphlets metaphor is a good one (and one I'm pretty sure I've heard at least one archivist use before)
@platypus@wndlb d) it's 'archived' on youtube and that's good enough until the channel is abruptly deleted over some long-retroactive censorship unrelated to the video in question
@wndlb no. We weed print based on use and space, which is certainly its own loss.
We lose digital because of a) negligence from publishers, b) publishers/hosts going under, but primarily c) things never being preserved in the first place and our inability to afford access to lots of content we'd like even at well-resourced institutions.
Journalists have seen whole back catalogs disappear offline and not been saved properly, etc.
