Bookshelf

Bookshelf is a collection of code, frameworks, utilities, and other resources. Many mods utilize Bookshelf's code base to power their own mods.

Why use a library mod?

Library mods such as Bookshelf allow seemingly unrelated mods to share parts of the same code base. This reduces the amount of time and effort required to develop certain mods and features. The Library's code base is also tested in a wider range of circumstances and communities which can lead to less bugs and better performance in mods.

Features for Players

While this mod is primarily for mod authors, there are a few useful features for Players.

- Debug commands like /bookshelf hand to get item IDs.

ABOUT THIS LISTING

This page describes Bookshelf by Darkhax. The description and screenshots are the author's own, imported from their listing on Modrinth on 31 August 2026: https://modrinth.com/mod/bookshelf-lib

Mythiq.net hosts no files for it. The download button goes straight to the release file on cdn.modrinth.com, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

MOD LOADER

This release is built for Fabric. A mod built for one loader will not load under another — Fabric mods do not run on Forge, and vice versa.

GAME VERSION

Built for Minecraft 26.1.2, 26.1.1, 26.1. Minecraft mods are tied to an exact version: a 1.21.4 build will refuse to load on 1.21.5.

THIS IS A LIBRARY

On its own it adds nothing you can see. It is here because other mods require it, and installing it is usually something another mod asked you to do.

DEPENDENCIES

Check the author's listing for required libraries before you start the game — a missing dependency shows up as a crash on launch, not as a warning.

1. Install Fabric for the Minecraft version you play, if you have not already.

2. Download the .jar with the button on this page. Do not unzip it — a mod jar is installed as it is.

3. Put it in your mods folder:

Windows — %APPDATA%\.minecraft\mods

macOS — ~/Library/Application Support/minecraft/mods

Linux — ~/.minecraft/mods

4. Launch the game with the Fabric profile selected.

ON A SERVER

Anything that changes world generation or gameplay has to be installed on the server as well as on every client. Client-side visual and interface mods do not.

UPDATING

Replace the old .jar rather than adding the new one beside it. Two versions of the same mod in the folder is a crash on launch.
