It doesn't matter. Archives are exempt from being forbidden to create copies due to copyright infringement. The Library of Congress can make all the copies it wants, it just can't SELL them. Now, there is a question whether a private company should legally be able to BE an archive of record, but as of now there's no legal reason they can't be, I believe. So it's legal.
