Iran leader warns of 'poisonous' books

Ayatollah Ali Khamenei, Iran's supreme leader, is urging censors to be vigilant against "harmful" and "poisonous" books. In an address to librarians and publishers this week, Khamenei warned: "Not all books are necessarily good. Some books are harmful," his official Web site said. Khamenei did not single out titles for banning, but works ranging from Plato's Symposium to the writings of James Joyce, Gabriel Garcia Marquez and Kurt Vonnegut have been blocked by the Ministry of Culture and Islamic Guidance - UPI
