It's all here, but my favorite moment might just be the simple joke in which, when listing the innumerable treasures of the library, we see a massive volume--"The Complete Works Of Émile Zola"--and then dolly out to reveal shelves of identical volumes: "Just how many giant books did Zola write? Infinitely many. Are they any less insurmountable than the 'indecipherable' Codex Peresianus? No."
Not only is this small camera movement hilarious, but this implicit question of the insurmountability of a body of work, of the history of human knowledge, of our own memory, is everything. Even if you manage to read all of Zola before you die (which you won't), it's just a thick volume on a shelf of thick volumes in a building full of shelves of thick volumes, in a world significantly bigger than France.
