Upvoted so hard.
Borges is pretty much my favorite writer of fiction. When I first read him, I frequently experienced a genuine sense of wonder that fiction hadn't ever evoked in me before (and hasn't really since, although Blindsight, Italo Calvino, The Book of the New Sun and some of Nabokov came close).
I recommend picking up his Collected Fictions. All his short stories, very well translated. Beautiful beautiful stuff.
If you haven't read much other Italo Calvino, "Invisible Cities" is really, really, really great.
This is the monthly thread for posting media of various types that you've found that you enjoy. I find that exposure to LW ideas makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this. Post what you're reading, listening to, watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing! To see previous recommendations, check out the older threads.
