Open it by: 1. Right-clicking while holding the Biology Dictionary book 2. Pressing the hotkey (default `` ` ``); Survival needs the book unless configured otherwise, while Creative can always open it The screen depends on what you are looking at. | Looking at | Opens | |------------|-------| | Block / Air | Home screen | | Entity | That entity's detail screen | | Beehive | Beehive info screen | | Straight up | Home screen (forced) | | Straight down | Your own detail screen | --- ## Obtaining How to get the Biology Dictionary book: > 1. In Creative mode, or when Survival hotkey access is enabled, the physical book is optional. > 2. The book is just `minecraft:writable_book` + NBT. No custom item is added. | Wandering Trader | Creative Inventory | |:------------------------------------------------------:|:--------------------------------------------------------:| |  |  | | In Survival, buy the Biology Dictionary from Wandering Traders. | In Creative, find it at the end of Tools & Utilities. | ### Survival Buy from **Wandering Traders**. Sell chance starts at 100% and gradually drops to 20% over time, without taking up any vanilla trade slots. > Easy to find early when you're broke, impossible to find later when you're rich (cue evil laugh)~ > > Kidding — it takes about **2 real-time days** (144 in-game days) to hit 20%. You'll be fine.
