A library extension (also known as a library module) is some code designed to be reused in a number of different games. Most authoring systems come with a standard library of code that provides the basic parser system and world model. Other authors then offer library extensions to provide other specific functionality: for instance, better NPC handling or more sophisticated simulation of some kind.
Authors can then choose to use these modules to add functionality to their games without having to reinvent the wheel.
