 In some cases, Soviet works even became copyrighted in other countries in the absence of any international copyright treaties.Prior to the accession of the Soviet Union to the UCC, only works by foreign authors that were first published in the USSR and unpublished works of foreign authors that existed in an objective form on the territory of the USSR were eligible to copyright.When the USSR joined the UCC in 1973 and the treaty entered in force with respect to the USSR on May 27, 1973, foreign works first published on or after that date outside of the USSR became copyrighted in the Soviet Union if

In addition to the UCC, the bilateral treaties the USSR concluded with several countries, amongst them also two Western countries, made works of nationals of these countries eligible for copyright in the Soviet Union, even works published before May 27, 1973.
