The distress and anger caused by the publication in a Danish newspaper of cartoons containing satirical depictions of the Prophet Mahommed is the starting point for an exploration of the dimensions of the right to freedom of expression contained in the United Nations Declaration of Human Rights. Related rights and duties to the community are examined alongside the explicit limitations on freedom of expression contained in the Declaration. The principles of harm and of offence as set out respectively by Mill and Feinberg are applied to the problem, and the concept of proportionality in interpreting laws, and the exercise of decorum in satirical comedy are also discussed. The need for librarians to adopt policies for controversial materials, which defend freedom of expression and freedom of access to information whilst respecting community sensitivities is reasserted.
