 Both Maes and Richard Taruskin cite an analysis of Borodin's manuscripts by musicologist Pavel Lamm, which showed that Rimsky-Korsakov and Glazunov discarded nearly 20 percent of Borodin's score.According to Maes, the result is more a collaborative effort by all three composers than a true representation of Borodin's intent.Lamm stated that because of the extremely chaotic state of Borodin's manuscripts, a modern alternative to Rimsky-Korsakov and Glazunov's edition would be extremely difficult to complete.
