I don't think that they are allowed to prepare copyrighted items for release in advance of them being in the public domain.
I prepared three of the works listed here for Standard Ebooks, and I’m not in the US so I’m definitely not covered by US copyright law on my own machine.
Why would that be the case? Copyright (at least in the US) only restricts distribution, performance and derivation.
