The ethical responsibilities of librarians, as well as statutes in most states and the District of Columbia, protect the privacy of library users. The First Amendment's guarantee of freedom of speech and of the press requires that the corresponding rights to hear what is spoken and read what is written be preserved, free from fear of government intrusion, intimidation, or reprisal. In seeking access or in the pursuit of information, confidentiality is the primary means of providing the privacy that will free the individual from fear of intimidation or retaliation.
Libraries are one of the great bulwarks of democracy.
They are living embodiments of the First Amendment because their collections include voices of dissent as well assent. Libraries are impartial resources providing information on all points of view, available to all persons regardless of age, race, religion, national origin, social or political views, economic status, or any other characteristic. The role of libraries as such a resource must not be compromised by an erosion of the privacy rights of library users. The American Library Association regularly receives reports of visits by agents of federal, state, and local law enforcement agencies to libraries, where it is alleged they have asked for personally identifiable information about library users. These visits, whether under the rubric of simply informing libraries of agency concerns or for some other reason, reflect an insensitivity to the legal and ethical bases for confidentiality, and the role it plays in the preservation of First Amendment rights, rights also extended to foreign nationals while in the United States.
