Leslie Klinger’s annotated Lovecraft with Joshi’s texts, now complete in two volumes in German translation. Das Werk II: Große kommentierte Ausgabe was published in Germany a few days ago.
Actually, thinking back… it was the Joshi texts that were used for the English edition. But I’m guessing that perhaps they swopped that out for a good German translation, already available?
Also, “Hypnos” was missing from the English edition for some reason. Also others. So not quite “Das Werk” complete that the publishers are implying.
