Children's Internet Protection Act (CIPA) Ruling

This case challenges an act of Congress that makes the use of filtering software by public libraries a condition of the receipt of federal funding. The Internet, as is well known, is a vast, interactive medium based on a decentralized network of computers around the world. Its most familiar feature is the World Wide Web (the "Web"), a network of computers known as servers that provide content to users. The Internet provides easy access to anyone who wishes to provide or distribute information to a worldwide audience; it is used by more than 143 million Americans. Indeed, much of the world's knowledge accumulated over centuries is available to Internet users almost instantly. Approximately 10% of the Americans who use the Internet access it at public libraries. And approximately 95% of all public libraries in the United States provide public access to the Internet.
