The Hungarian government has long demanded the return of the 134 books, which were originally kept in a Calvinist college library in the eastern town of Sarospatak. They were transferred to two Budapest banks during the war for safekeeping, but were seized by victorious Soviet troops in 1945.
The books are currently in Nizhny Novgorod in central Russia.
