The Canadian Library Association has posted its new statement on intellectual freedom http://bit.ly/1My5mZd (PDF). I like how they've approached the issue, stating:
".. the Canadian Library Association affirms that all persons in Canada have a fundamental right, subject only to the Constitution and the law, to have access to the full range of knowledge, imagination, ideas, and opinion, and to express their thoughts publicly."
That libraries have core responsibilities to
"…safeguard and facilitate access to constitutionally protected expressions of knowledge, imagination, ideas, and opinion, including those which some individuals and groups consider unconventional, unpopular or unacceptable."
"…safeguard and foster free expression and the right to safe and welcoming places and conditions."
" safeguard and defend privacy in the individual’s pursuit of expressive content."
"…libraries resist efforts to limit the exercise of these responsibilities while recognizing the right of criticism by individuals and groups."
