Index on Censorship works in partnership with major groups working for freedom of expression rights, including Amnesty International, the American Civil Liberties Union (ACLU), Liberty, English PEN, PEN International, Human Rights House Network and IFEX among many other groups to create landmark events of national and international significance.
Index on Censorship is a founding member of the International Freedom of Expression Exchange, a global network of non-governmental organisations that monitors censorship worldwide and defends journalists, writers, Internet users and others who are persecuted for exercising their right to freedom of expression.
