Although this is about authors, I'm putting this here because it is not even remotely a serious literary discussion and seems better suited to the light-hearted discussions here.
I organize my library by country of the author and while most of the time, this is an easy classification, there are those authors that leave me doubting the wisdom of this choice. Case in point: Arthur Koestler, he was born in Hungary, educated in Austria but eventually became a naturalized British citizen...where the heck do I put him?! I had this quandary with Milan Kundera, he was born and raised in Czechoslovakia but emigrated to France, half of his books were originally written in Czech, half in French, but really, he is and will always be Czech to me so I didn't hesitate too long with that one. And then there was O.E. Rolvaag, born and raised in Norway but emigrated to the US in his early twenties. His books, I think, were all written after he moved here, they are largely about the immigrant experience and take place in the Dakotas and Minnesota but yet in the end, I stuck him with the Norwegians because his 'voice' is so Scandinavian and I believe he actually wrote them in Norwegian and were then translated, it just seemed wrong to stick him with the Americans. But this Koestler guy...I have no idea! The book I'm reading is actually about the Stalinist purges of the old regime from the '30s so that doesn't lead me one way or the other so what do I do? Go with where he was born? Where he went to school? Or where he eventually ended up? Opinions please! I need to be guided!
