AutoLibrarian

AutoLibrarian is a Minecraft hack that enables players to automatically train a villager to become a librarian and sell a specific enchanted book. By using this hack, players can set up an entire trading hall quickly and easily.

The hack provides several settings, including a “Wanted books” list where players can plan out which books they want villagers to sell in their trading hall, “Lock in trade” to prevent villagers from changing their trade offers, “Update books” to automatically keep the book list up to date, and other settings to customize the hack's behavior.

When using AutoLibrarian, it's important to make sure that the villager can't walk away and can't block the player from placing the job site. A setup like ianxofour's “Instant Trading Hall with Villager Breeder” works great with AutoLibrarian and is cheap and easy to build, too.

The “Wanted books” setting is a custom “BookOffers” setting type that is only used by AutoLibrarian. It is a list of book offers, which each have an enchantment, a level, and a maximum price. The enchantment and level are used to determine which books the villager will learn to sell, while the maximum price is used to determine how much the villager will sell the book for. The maximum price can be set to 64 to disable it, which means the villager will sell the book for whatever price it wants.

The “Lock in trade” setting allows AutoLibrarian to automatically buy something from the villager once it has learned to sell one of the books that the user wants. This prevents the villager from changing its trade offers later, which is especially useful when the user is running AutoLibrarian in the background while they are doing something else.

As it says in the in-game description, the user should make sure they have enough paper, emeralds, and books in their inventory before using this feature. If the user doesn't have enough items to complete a trade, AutoLibrarian will fail to lock in the trade and the villager will be able to reset its trade offers.

The “Update books” setting allows the user to automate their “Wanted books” list. If this setting is enabled, AutoLibrarian will automatically remove books from the list when a villager has learned to sell them, or update the maximum price for the book so that the next villager has to sell it for a cheaper price.

The “Range” setting determines how far AutoLibrarian will be able to reach to place the job site, break the job site, and interact with the villager.

The “Facing” setting determines how AutoLibrarian will face the villager and job site.

“Client-side” is the most legit option. It actually moves the player's camera to face the villager and job site. However, it can be a bit disorienting to look at.

“Server-side” is the default option. It moves the player's head on the server-side, but still lets the player move their camera freely on the client-side. This is recommended for most users.

“Off” won't face the villager at all. This is the least legit option and will be detected by anti-cheat plugins.

The “Swing hand” setting determines how AutoLibrarian will swing the user's hand when interacting with the villager and job site.

“Client-side” makes the animation visible to both the user and to other players. “Server-side” only makes it visible to other players. “Off” won't swing the hand at all, which can be detected by anti-cheat plugins.

The “Repair mode” slider prevents AutoLibrarian from using the player's axe when its durability reaches a certain threshold. When the durability of the axe reaches this threshold, the setting will prevent the axe from being used until it is repaired. The slider can be adjusted from 0 (off) to 100 remaining uses, in increments of 1.

• When a villager is done training, place a sign against the lectern with the enchantment and price written on it. This helps to keep your trading hall organized.
