What today's Open Library books reveal
The list rotated from YA crossover (Red Queen, Glass Sword, Pride and Prejudice) back to self-help and money titles: Atomic Habits, Psychology of Money, Rich Dad, 48 Laws, Think and Grow Rich. Potter remains, but as two volumes at 3 and 7 rather than a single lead. Camus at 10 is the only literary leftover after Alchemist dropped. That is a finance-shelf day, not a fantasy-shelf day.
