According to Mojang<ref>Template:Snap</ref>, librarian trades are considered to be too overpowered compared to using an Minecraft:enchanting table or searching for Minecraft:enchanted books. With the new changes, Minecraft:players must explore Minecraft:villages in different Minecraft:biomes and unlock villager tiers instead of relying on random chances. Wandering traders had unfair prices and didn't sell many useful items. With the new changes, their prices are lowered, more trades are added, and they can also purchase items from the player. Additionally, various Minecraft:explorer maps were given to Minecraft:cartographers to make it easier for players to locate specific biomes.
Instead of offering every possible enchanted book, librarians now offer specific enchanted books depending on which biome they come from.<ref group="note" name="nonatural">Villages do not generate naturally in jungle or swamp Minecraft:biomes, but they rarely expand into these biomes when generated in the border(s) of other biomes. Usually, players must breed villagers or cure zombie villagers in these biomes to access their trades.</ref>
All tradable enchanted books are now split to special books and common books.
Special books have a specific enchantment with a fixed level, and are available only from master librarians with full XP.
Common books have a specific enchantment without a fixed level, just like before.
The price of a book in emeralds depends on the enchantment level and "treasure" status. The minimum price of a book is given by 2 + 3 * (enchantment level), while the maximum price is 6 + 13 * (enchantment level), capped at 64. The possible values are 5–19 emeralds for Lvl I, 8–32 for Lvl II, 11–45 for Lvl III, 14–58 for Lvl IV, and 17–64 for Lvl V. For Minecraft:treasure enchantments the price is doubled (but still capped at 64). All values are equally probable.
Buying diamond armor now also requires a small amount of diamonds.
Most master-level armorers buy iron blocks and pay 4 emeralds for them.
Chainmail armor is exclusively sold by jungle and swamp armorers.
The savanna armorer sells cursed diamond armor at reduced prices.
The taiga armorer can swap one piece of diamond armor for another. Damaged, enchanted, and cursed armor are accepted, making 8 the minimum number of diamonds required for a full set.
Added seven new maps which Minecraft:cartographers can sell, depending on the biome they come from.<ref group=note name=nonatural />
