Aziraphale, still very confused, easily shakes off the earlier comment in favor of talking with a possible fellow lover of the written word. He's still not a librarian, though. But it's getting harder to fend off the idea when he doesn't have a space to keep his own books away from prying eyes and touching hands. He can't be selfish about it here (even though he really wants to).

"When it first appeared, the collection that showed up with it was mostly everything that was already on the train, I believe. Back then it was barely a shelf." People making due with what they had, he suspects.

"The option for a library was offered and voted on, but I supposed we must've missed the fine print."
