 In 1885 Belyayev created the publishing house "M. P. Belaieff" in Leipzig to secure international copyright to Russian composers; until then, international copyright did not extend to music published in Russia.Eventually, he published over 2000 compositions by Russian composers, the first of which was Glazunov's "Overture on Greek Themes".The works published there were edited to a high standard, while the authors received higher fees than was usual and kept full control over performance rights.
