In an apparent reversal of decades of U.S. practice, recent federal Office of Foreign Assets Control regulations bar American companies from publishing works by dissident writers in countries under sanction unless they first obtain U.S. government approval.
The restriction, condemned by critics as a violation of the First Amendment, means that books and other works banned by some totalitarian regimes cannot be published freely in the United States.

In a further wrinkle, even if publishers obtain a license for a book -- something they are loathe to do -- they believe the regulations bar them from advertising it, forcing readers to find the dissident works on their own.
"It's absolutely against the First Amendment," fumed Arcade editor Richard Seaver, who hopes to publish an anthology of Iranian short stories. "We're not going to ask permission (to publish). That reeks of censorship."
