About this site

Grand Book Archive Companion is an independent website about The Grand Book Archive: Tidy Up!. It is not operated by or affiliated with InBlue Games.

What the guides help you do

Resolve shelf-sorting and book-stack problems, compare upgrade decisions and follow version-specific controls.

How the information is prepared

We compare public developer announcements, store and support pages, and relevant community accounts. Sources are linked beside the relevant facts or in the page’s source section. A public source check is not a claim of personal gameplay testing.

For changing systems, the page identifies the version or review date. Community routes and editorial recommendations remain separate from official rules. If sources disagree, we explain the disagreement instead of inventing a precise result.

Images and independence

Game screenshots and promotional art are credited to their respective creators. Images illustrate the game context; they do not prove an exact route, test result or current interface unless explicitly described that way. This website does not host unofficial game installers or ask for game-account credentials.
