I don't think HN commenters need to be the arbiters of which books are beneficial to society.

And beyond just benefit to society, don't forget how subjective the decision about what constitutes a "unique artifact" is. That random product manual from 1966 becomes a near-priceless relic to me if it lets me repair and use the sewing machine handed down from my grandmother. Not necessarily the ink printed on paper, but the information contained within.

The above is based on a true story involving archive.org's Manual Library. The idea that even such esoteric and forgotten information would get hoovered up into the walled garden of Amazon's AI and then destroyed in the outside world, such that I have to go pay them to access even a facsimile of it, is frankly disgusting.
