"All works under copyright protection that are published in the United States are subject to the mandatory deposit provision of the copyright law (17 USC section 407).
This law requires that two copies of the best edition of every copyrightable work published in the United States be sent to the Copyright Office within three months of publication. Works deposited under this law are for the use of the Library of Congress"
I don't know how/if it works in practice, but if the copyright is supposed "To promote the Progress of Science and useful Arts", I think that it is perfectly fine for the LOC to guarantee that when the copyright expires at least a copy is still around.
This doesn't mean that it should provide universal access though, especially while the copyright is still valid.
I have no idea :-). Frankly I was under the impression that this requirement had been weakened/removed over the years, but this is what they write on the official website and I cannot find any reference about that so that's why I wrote "how/if it works in practice"
(maybe the devil is in the referenced details, but alas I have not time to investigate now)
But my point was more about the matter of principle: it is reasonable for the government to ask a copy of the works (for preservation reasons) in exchange for time-limited rights over it.
I mean, it certainly doesn't apply to 80 year-old 78s published long before the law said that. They don't go looking for ancient stuff that predated that practice.
