Books and Shelves
Storage Books trade how many item types they hold against stack depth. Use any Storage Book on a vanilla bookshelf to make the conversion-only Storage Bookshelf; it has no standalone recipe.

Power and Connection
Everything with an item form stays in the Aura creative tab. Connect shelves to a Bookshelf Coordinator with clear lines of sight, then place a powered Aura network block beside it. Right-click empty-handed to open the browser. Draw rises with shelf count: 5 power for one shelf, 31 for five, 81 for ten.

Search and Retrieve
Search localized item names, scroll the 9-by-3 results, select a stack, set an amount or choose Max, then press Retrieve. The browser groups matching items with identical data components.

Deposit and Withdraw
Use the Coordinator while holding an item to deposit. Sneak-use it empty-handed to withdraw the first stack. Full counts can exceed 64; incomplete, unloaded, unreachable, or unpowered networks disable actions. Stored items remain in their books.
