The bottom line now seems to be that CO [Copyright Office] can no longer require the deposit of two copies of all published works. Deposit can, it appears, continue to be a condition of copyright registration, but in light of this ruling it seems only a matter of time before that requirement is challenged as well. . . .
The implications of this ruling for the Library of Congress are potentially significant — if for no other reason than it will now have to purchase many of the books it once could rely on publishers and authors providing gratis.
