American libraries are taking steps to guard patrons’ privacy from the US government. The US Patriot Act allows law enforcement to pry into the library habits of citizens. “The American Libraries Association calls the provisions a present danger to the constitutional rights and privacy rights of library users. The association fears library patrons or bookstore customers could become targets of suspicion simply based on what books they are reading. More importantly, they say they fear a chilling effect that could make people fearful of reading particular books or Web sites to avoid becoming targets of suspicion.”
