@Cryspeg That's a typo of some kind. There haven't been 18 trillion books printed since the printing press was invented. Even if there were, all of Amazon's servers combined wouldn't have enough memory to store even half that number.
@POOetryma it was so weird. I mean I have a lot of books (about 1800) but not THAT many books lol. Yeah not that many books for sure. I’ve never seen a message like that before.
Actually I woke up to a black cat lol
