Does this have variable text on it? I didn't get De Rerum Re but rather The Little Book of Hearts.

I also wonder if the text changes based on what you have in your inventory. I only have an extensive collection of Bazaarine poetry with 19 slim volumes, not a "very extensive" one. There's also Anatomies of Aquatic Life-forms, which the FLPC literally creates (the novels, too, might be something of your creation, given that you can write novels in court). There's a lot here that could be variable text based on your inventory.
