" Repository,” he finally says, “you know this word? A resting place. A text—a book—is a resting place for the memories of people who have lived before. A way for the memory to stay fixed after the soul has traveled on.” His eyes open very widely then, as though he peers into a great darkness. “But books, like people, die. They die in fires or floods or in the mouths of worms or at the whims of tyrants. If they are not safeguarded, they go out of the world. And when a book goes out of the world, the memory dies a second death. "
