How does the Abbot describe the library? Explain in your own words.

From the text:

The library was laid out on a plan which has remained obscure to all over the centuries, and which none of the monks is called upon to know. Only the librarian has received the secret, from the librarian who preceded him, and he communicates it, while still alive, to the assistant librarian, so that death will not take him by surprise and rob the community of that knowledge. And the secret seals the lips of both men. Only the librarian has, in addition to that knowledge, the right to move through the labyrinth of the books, he alone knows where to find them and where to replace them, he alone is responsible for their safekeeping.
