# Standard Method Library Overview

A Method Library is a physical container for method plug-ins and method configuration definitions. All method elements are stored in a method library.

Much like a library has books, a method library has method plug-ins. Where a library book is made up of sections or chapters and content within those chapters, method plug-ins are made up of method content and processes. Method content contains content packages and both standard and custom categories, while processes structure this content into process fragments called capability patterns and full lifecycle processes called delivery processes.

A method library also has one or more method configurations that filter the library and provide smaller working sets of library content for the end user.
