There have been three projects to publish critical editions of Tchaikovsky's complete works:
- Complete Collected Works (Moscow; Leningrad, 1940-1991), encompassing almost all of Tchaikovsky's music and writings in 107 volumes (Russian only).
- New Complete Edition of Tchaikovsky's works (Mainz; Moscow, 1993-), of which only five volumes have so far appeared (Russian and English).
- Academic Edition of the Complete Works (Chelyabinsk, 2015-), in progress (Russian and English).
