This document is composed of: terms currently used in metadata in the ADL Catalog, with definitions and sources; and an alphabetical list of all terms. Terms are derived from the Dublin Core (http://dublincore.org/documents/dcmi-type-vocabulary/) and the Library of Congress Subject Headings (LCSH; for ordering information, see http://www.loc.gov/cds/), modified and expanded to accord with the current holdings of ADL.  As new collections are added, new terms will be added.
