Scope note:

Finding aids developed at the Library of Congress to describe groups of papers, collections, and records by giving their provenance and conditions of administration, their scope and general content, including span and bulk dates, biographical notes about the person, group, or organization whose material it is, its arrangement, a container or folder listing, and, on occasion, selective document indexes.
