The Cosmic Library explores massive books in order to explore everything else. Here, books that can seem overwhelming—books of dreams, infinity, mysteries—turn out to be intensely accessible, offering so many different ways to read them and think with them. Season one considered Finnegans Wake; in season two, it was 1,001 Nights. Season three journeyed through and beyond the Hebrew Bible. In season four, we considered Journey to the West. For season five, we talk about a kind of writing that's filled many massive books: the American short story.
