What today's Open Library board reveals
The list flipped from a Potter-led mix of kids and canon to adult self-help on top and 19th- and 20th-century assigned reading at the bottom. Atomic Habits at 1 plus Housel, Greene, Wiest, and Kiyosaki is a money-and-habits block.
Potter dropping 4 places without leaving the ten is a fade, not an exit. Romance and middle-grade (Haunting Adeline, Wimpy Kid, Secret Garden) are the drop-offs.
