EFF says:
This year marks the 10-year anniversary of the enforcement of the Children’s Internet Protection Act, CIPA, which brought new levels of Internet censorship to libraries across the country. The law is supposed to encourage public libraries and schools to filter child pornography and obscene or “harmful to minors†images from the library’s Internet connection in exchange for continued federal funding. Unfortunately, as Deborah Caldwell-Stone explains in Filtering and the First Amendment, aggressive interpretations of this law have resulted in extensive and unnecessary censorship in libraries, often because libraries go beyond the legal requirements of CIPA when implementing content filters. As a result, students and library patrons across the country are routinely and unnecessarily blocked from accessing constitutionally protected websites.
