Honestly, it already happened. Books from before copyright became effectively infinite are widely available. Recent books are widely available. Anything in between (1930-1980) is a gulf of missing books. https://www.theatlantic.com/technology/archive/2013/07/the-hole-in-our-collective-memory-how-copyright-made-mid-century-books-vanish/278209/ https://www.theatlantic.com/technology/archive/2013/07/the-h... I like reading old pulpy science fiction. They are typically out of print, and will never have a reprint. I'll find a reference online, but won't be able to find a copy. There might be a plot summary, or a listing of which out-of-print magazines initially carried the story, but no copies. As another example (and please somebody prove me wrong), I cannot find the 1954 movie "So This is Paris", starring Tony Curtis. No copies available anywhere on amazon, ebay, or searching through internet sites. There was a short clip of one of the songs on Youtube a few years ago, but it was taken down for copyright infringement. I simply cannot find it anywhere.
