I try to keep support up for the latest drop of Minecraft. Updates to newer Minecraft
versions may be delayed from time to time, as I do not always have the time to immediately update my mods.

Unsupported versions are still available to download, but they won't receive new features or bugfixes.

NeoForge ports are available for Minecraft 26.1 onwards.

Usage

The Fabric API is required on Fabric.

This mod adds one simple command, /bookcopy. It can be used as follows:

  • /bookcopy export <name> [<overwrite>] - exports the contents of the book you're holding to the given filename.
    • Set overwrite to true to overwrite books.
  • /bookcopy import <name> [<sign>] - reads the contents of given filename and writes it to the book you're holding.
    • Set sign to true to automatically sign the book after importing it. Only works if the book was saved with a title.

When exporting, you can use a written book or a book and quill to read from. When importing, you can
only use a book and quill, since the contents of a written book can't be updated.

Book contents are stored in the .minecraft/config/bookcopy folder. Book contents can be
transferred across worlds.

Below version 0.1.2-1.21.1, book contents are stored in NBT. In version 0.1.2-1.21.1 support for
reading JSON files was added, by adding .json at the end of your save names. JSON books are stored
in the following format:

{
  "title": "Signed book title",
  "pages": [
    "This is a signed book.",
    "This is the second page!",
    "",
    "An empty page then this!",
    "Wow."
  ]
}

Frequently Asked Questions

Book Copy server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Is Book Copy compatible with fabric and neoforge?

Book Copy officially supports fabric, neoforge for Minecraft 26.1.2, 26.1.1, 26.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Book Copy – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Book Copy consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
