[Op-Ed] New York Times; The Public Domain:

"Copyright gives writers and others the incentive to create by giving them exclusive right to their work. But Congress’s power to grant copyright is limited in time and scope so that works can move into the public domain, where they become an essential part of our culture. The government must find other ways to comply with the trade treaty without curbing free expression."
