Sure, and nobody is going to the library or other archives to check out those old how-to books, they're using contemporary sources on Youtube instead. And the same will be true of old vs contemporary sources in fifty years. I don't expect my own collection of books - which includes some that are valuable to me primarily for nostalgia - to have much value past the death of myself and the rest of my generation. It might temporarily have a lot of monetary value near my death - when other copies have already been lost - but to someone born fifty years after me? What use would pulp fiction from the 80s be to many of them? My parents and uncles are in a bit of disbelief of how little even I care about the Beatles already, after all.
