In Russia, the duration of copyright protection differs from that in the United States.
As of 2022, the general term of copyright protection in Russia is the author’s lifetime plus 70 years after their death. For works created anonymously, pseudonymously, or under a collective pseudonym, the term of protection is 70 years from the date of first publication. For audio-visual works, such as films, the term of protection is 70 years after the death of the last surviving author, or 70 years from the date of first publication if the authors are unknown.
It’s essential to verify the specific copyright status of any work, as there may be exceptions or nuances in copyright law, particularly regarding restored or remastered versions of older works.
Therefore, works published in 1909 would likely be in the public domain in Russia, as more than 100 years have passed since their publication.
To verify the specific copyright status of works published lets say in 1909, particularly in Russia, it would be advisable to conduct due diligence through a thorough copyright search in connection with copyright law in Russia.
