The Iranian legislators changed the copyright law by removing its time limit entirely. From now on, any copyrighted work will be the property of the creator and his/her inheritors indefinitely. And if at any given point of time, there are no more inheritors, the copyrighted work will be passed on to the supreme leader! So we should forget about a Project Gutenberg equivalent for Iranian works. The ISNA report rationalizes the passing on of the work to the supreme leader as "for public use," that is the work will be owned to the leader so that he can use it "for the public benefit" as he sees fit. Again here's a typical behavior of the Islamic regime. Instead of passing something directly to the people (as in other countries in which the work goes to the public domain after a certain amount of time), it is handed to the authorities, because they see themselves the only ones who know the good of people.
UPDATE: A friend told me that the law has been vetoed by the Guardian Council, though I can't find any sources to corroborate the story.
