The Discworld, by the numbers
Forty-one novels read span by span — every line of dialogue attributed, every scene located, every bit of gossip logged. Who really speaks the most words? Which city hosts the most story? Who gets discussed most often behind their back? All of it counted. None of it invented. Probably.
This was a slow project done properly: each book annotated passage by passage, then checked, then counted. All forty-one novels are in the tally, and a book only ever joined it once every one of its words had been accounted for.
