In the new versions Minecraft, the encyclopedia panel is attached to the interface upon opening the inventory or any tool for creating and processing items. This is a good cheat sheet that speeds up the process of creating new items: when you select any item from the list of its blueprint is automatically loaded into the interface of creating items. This reduces the need to memorize blueprints and speeds up the creation of new items. You also have the option to change the filters: display only the objects you can currently create.
The encyclopedia, however, has one big flaw: some of the items available for production appear together with the acquisition of new assets or the manufacture of semi-finished products. However part of blueprints need to be discovered by you alone (or found in our guide), so they will not appear in encyclopedias automatically, and only after you create them yourself.
