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.
