as an editor, i hope we hire a bunch of iranian authors soon. because then, it would be illegal for me to edit those books. according to the nytimes:
Anyone who publishes material from a country under a trade embargo is forbidden to reorder paragraphs or sentences, correct syntax or grammar, or replace "inappropriate words," according to several advisory letters from the Treasury Department in recent months.
Adding illustrations is prohibited, too. To the baffled dismay of publishers, editors and translators who have been briefed about the policy, only publication of "camera-ready copies of manuscripts" is allowed.
The Treasury letters concerned Iran. But the logic, experts said, would seem to extend to Cuba, Libya, North Korea and other nations with which most trade is banned without a government license.
