From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
The Library is a huge, unwieldy model with tons and tons of information in it. It also contains a smattering of human inhabitants, who run around the Library doing silly things like killing each other. In other words, the Library is a lot like the universe. Borges is even nice enough to come right out and tell us so in the very first line: "The universe (which others call the Library)..." You know the rest. The symbolic significance of the Library isn't exactly hidden here, but hey – this story is tricky enough as it is. It's sort of nice to have a gimme.
