A first story-identification question has just been asked and I think it would be best to discuss here whether we want to allow such questions and if yes, under which conditions.
Such questions could discuss the finer points of German language insofar as we could analyze their vocabulary, style and rhetoric figures to make out the author. So if the text
is (almost) complete and
seems to be a piece of poetry, drama or major form prose,
then I think we should give it a shot. We could actually rediscover some art pieces for the internet. Apart from that I don't see any danger of getting overwhelmed by such questions.
