Copyright enforcement or censorship: new uses for the DMCA?

Section 512 of the Digital Millennium Copyright Act (DMCA) has a provision that protects ISPs from liability for transmitting copyright violations-as long as they have and follow a process for removing infringements when notified of them. Given the DMCA's wording, any attempt to be sure that we will know in the future what was said today will depend on clarifying the rights and responsibilities of libraries and the archive organizations that have traditionally maintained historical records; the special status of the US Library of Congress and the US National Archives and Records Administration might be of use here.
