Eccentric Tome Mod FAQ

Combine a book and a bookshelf in a crafting grid to create the Eccentric Tome. The recipe is shapeless, so the exact arrangement of the two ingredients doesn't matter.

Hold the Eccentric Tome and right-click (or use the bound key) while holding the guidebook you want to store, or open the Tome's interface and place the book inside. Once stored, the original book is consumed and its contents live inside the Tome.

Open the Eccentric Tome's interface and select the stored book you want to retrieve. The book is returned to your inventory and removed from the Tome's storage.

The Tome supports guidebooks from mods like Patchouli and Tinker's Construct, along with other mods that register their books as compatible. If a book won't go in, that mod likely hasn't added Eccentric Tome support.

Generally no — the Tome is meant to hold one of each guidebook so you don't duplicate entries. Trying to add a second copy of a book you already stored typically does nothing or is rejected.

The book's mod probably doesn't support the Eccentric Tome, or you already have that book stored. Check that the book is a registered guidebook and that it isn't already inside the Tome.

Yes, the stored books live inside the Tome item itself, so losing the Tome loses its contents. Keep it somewhere safe or in a secure storage rather than carrying it into risky situations.

Yes, Patchouli guidebooks are among the main supported types. As long as the Patchouli book is a standard guidebook item, it can be stored and retrieved through the Tome.

Yes — selecting a stored book in the Tome's interface opens it for reading. You only need to retrieve it if you want the physical item back in your inventory.

No, the Tome is a lightweight item that just stores references to guidebooks, so it has negligible impact on performance. Any lag you see is almost certainly from another mod or the guidebooks themselves.
