Ten Queen's Domain books go on shelves: six for the numbered shelves of the Tower of Knowledge library and four for the god shelves in the Record of Sin. Each bookcase shows a symbol with one gap on the shelf below it, so the puzzle is always the same shape, matching a title to a gap. Two more books are lore only and fit no shelf at all.

The Queen's Domain books on the six Tower of Knowledge shelves
A Missing Books notice in the library lists six numbered shelves, and each title goes on its own shelf.
| Shelf | Category | Book | Where to find it |
|---|---|---|---|
| I | Alchemic Recipes | The Great Work IV: Rubedo | On an altar in the cave below the Cemetery on the starting island, the cave with an egg outside; go down the stairs and dash to the altar beside the pedestal with the throwable stone block |
| II | Fantastical Creatures | The History of Dragons | A reward from Knowledge Keeper Wourha once you have reported enough bestiary entries; if she does not hand it over, explore more and come back |
| III | Construction Techniques | Dams and Weirs | Bottom shelf of the bookcase beside the tower teleporter |
| IV | Fairy Tales | Upim's Fairy Tales | A hidden cave on the Obmuer Temple side of the island; you need three air dashes to cross, then drop into the pit with the giant tree and dash up to the ledges near the top, where the book is beside a skeleton and a food pickup |
| V | Eldritch Horror | The Old Ones Beyond | Behind the secret wall above the library room entrance, reached from the stairs right after the trap floor; kill the skeleton inside and the book drops |
| VI | Queer Romance | Koko's Sapphic Adventure | In the upper library rooms near Wourha's area, a normal pickup rather than a quest reward |
The Tower of Knowledge walkthrough has the route through the tower.
The four god books in the Record of Sin
The library in the Record of Sin has a symbol above each of four bookcases with one gap on the shelf below it, and each gap takes the book belonging to that god.
| Symbol | God | Book | Where to find it |
|---|---|---|---|
| Circles | Sipeha | Monarch of the Void | From Bones of Archivist Inha in the Tower of Knowledge: drop into the basement, take the ramping corridor from the room with the stone statue, and find the sitting skeleton holding a Radiant Fruit, with the secret door on the wall right next to it |
| Eight-pointed star | Puwema | The Green Goddess | Teleport to Deimpo Mausoleum, go down the spiral stairs toward Chef Gagi and press interact on the walls until a secret door opens, then dash across to the ledge opposite, where the book is on a small pedestal near an Occultist Josami Warden |
| Cross | Wodaso | Wodaso's Embrace | In the Rare Artifact Storage room that you open by finishing the six shelf books; look closely, it is easy to walk past |
| Three diamonds | Jigeki | The Rotting God | A hidden room in Obmuer Temple near the needle throwing weapons, with Candle Crawlers around it |
Shelving all four spawns Daji the Grasping, a spear at the centre of the Record of Sin library whose description reads 'It steals strength from those it pierces.'
The Memento Mirror guide has the Record of Sin route.
The Rare Artifact Storage room
The Rare Artifact Storage room, the golden door with the armour and two gargoyles, stays shut until all six shelf books are in place. It holds the Crushing Lance, and finishing the shelf set is also what unlocks the room that contains Wodaso's Embrace.
You do not need the six to progress. Returning every lost book is what the I'm Not Paying the Late Fee achievement tracks.
The puzzle guide has the other puzzle rewards.
Books that fit no shelf
The Ratty Bug Compendium and The End of Epha are lore only and fit no shelf. The Rotting God fits no Tower of Knowledge shelf, which is why it goes to the Record of Sin instead.
The shelves are also the reason the tower has a bestiary quest attached to them. Shelf II, The History of Dragons, only appears once you have reported enough entries to Knowledge Keeper Wourha, so filling the library feeds the bestiary and the bestiary feeds the library.
The bestiary guide lists the enemies that drop the rest of the collection.
