Thaumonomicon (Thaumcraft 4)

The Thaumonomicon is an item added by the mod Thaumcraft 4 that is used to record and explain all research.

The Thaumonomicon will display a UI that shows the tech tree and several tabs. When an item on the tech tree is clicked, it will explain the creation of that item, and what it is used for. To obtain one, right click a bookshelf with any wand.
