Copyright and the Russian Internet

I suppose that many musicians are familiar with Russian online sources from where you can obtain sheet music or writings that are not yet in the public domain. In fact, it would surprise me if somebody told me that, as a musician, they had never heard of ScorSer, the Tarakanov Archive and the likes. Yet there is one case that I find particularly striking: the website www.kholopov.ru, dedicated to the work of Yuri Nikolayevich Kholopov, includes an electronic library that offers scans of comparatively recent Russian, English, and German musicological and music-theoretical publications, and as such poses multiple copyright infringements under the name of one of the most prominent Russian music scholars of the twentieth century. I imagine it is very unlikely that this is going to change, given the current situation, but that doesn’t mean we needn’t be aware of this and similar cases. — NB: In 2004, the term of copyright protection in Russia has been extended from 50 to 70 years post mortem auctoris.
