During Perestroika, the law and the administrative procedures were changed piece by piece, relaxing the governmental control over authors' exercises of their copyright. The official royalty rates were dropped, and the state monopoly on foreign trade on copyrights was abolished. Authors for the first time could legally negotiate publication contracts with foreign publishers themselves. A new, profoundly revised Soviet copyright law was passed in 1991, but the Soviet Union was dissolved before it could enter in force.
