This Mark Harman translation Amerika: The Missing Person (Work) – BookBrainz of Kafka’s Amerika was taken from a different text: Der Verschollene: Kritische Ausgabe (Work) – BookBrainz
To give the Harman translation a relationship to Amerika, I used the relationship “is derived from”.
The only way I could credit Jost Schillemeit as the editor of Der Verschollene: Kritische Ausgabe Work was use the relationship “was revised by”.
Not sure if this is the correct method!
