Best First Route

Check the shelf map so the 1A-2Q labels make sense before you start sorting random piles.
Grab the Crimson Octagon Key and unlock High Jump.
Collect the other chest upgrades before a long route: Carry Capacity +3, Run, and Carry Capacity +2.
Organize one shelf section at a time. A row only counts when every same-title volume is together and in order.
If you get stuck near the end, use the 399/400 checklist instead of rechecking the whole library blindly.
