This item is added by Thaumic Tinkerer. Once the item is bound to a player, any other player which uses the tome will gain the research nodes the bound player has already discovered. This is particularly useful for people playing cooperatively who don't want to have to repeat the research activity.
To craft the tome, place a Thaumonomicon in the centre of crafting grid with paper to the sides and below, and a scribing tool above.
Firstly the player who wishes to share their research with others holds the item and uses it. It is now bound to that player.
Next the player who wishes to receive the research holds and uses the item. Their research has now been filled in with all the research the other player has already discovered.
