I just stumbled on what looks like a fantastic tool: the website Compare Translations. It’s just what it sounds like. Try their page for Fathers and Sons. They also have Dostoevskii, Tolstoi, Lermontov, others. No Leskov yet. I’m not sure how long they’ve been around or whose idea it was, but my thanks to whoever is behind it! It should be very useful whether you know the source language of the translation or not.
