Secret and mysterious libraries

spooooky

While real-world libraries are, sadly, corporeally and temporally fixed (and, as far as I know, have never employed an orangutan as Head Librarian), there are still plenty of examples of libraries around the world that are secret or restricted, dealing with very different kinds of texts to the public libraries we know and love. While several of these libraries have now opened up, at least partially, their histories are still fascinating, and learning about them has that special spark of uncovering a secret.
