Bookshelf Mod 1.19.2, 1.18.2 includes a set code and API for mods by the author in Minecraft (it must be installed for use).
Bookshelf Mod is a supporting mod that will not affect Minecraft when installed independently. It will instead allow other mods to run. Bookshelf Mod supports mods with a common code structure. It will optimize the system, reduce file size, save time and cut down on the file’s size. This code has been combined into Bookshelf Mod. It is important to note that this mod must be installed before you use basic mods. If not installed, the game will throw errors and you can’t load the game until your log in!
