While MARC is still considered an efficient method for describing archival resources, with EAD and DA:CS — and using data values drawn from Library of Congress vocabularies — archives have a full complement of data standards for describing archival materials. The wealth of information in finding aids is no longer locked away in remote repositories, but rather can be shared broadly online and via content aggregators. The development of Metadata Encoding and Transmission Standard (METS) as a method for encoding and sharing item-level digital objects within finding aids, such as digitized archival photographs and individual letters, also supports the increased sharing and distribution of archival content.
