Describing Archives: A Content Standard
Encyclopedia
Describing Archives: A Content Standard (DACS) is a set of rules for describing archives, personal papers, and manuscript
collections. The descriptive standard can be utilized for all types of archival material. In 2004, DACS was adopted by the Society of American Archivists
as an official SAA standard.
. DACS also provides crosswalks from DACS to MARC
and Encoded Archival Description
(EAD). DACS specifies only the type of content, not the structural or encoding requirements or the actual verbiage to be used; it is therefore suitable for use in conjunction with structural and encoding standards such as MARC and EAD and with controlled vocabularies such as MeSH
, LCSH, AAT
, and so on.
It should also be noted that DACS is the US implementation of international archival descriptive standards such as ISAD(G)
and ISAAR(CPF).

It has now been widely adopted by the archival community throughout the United States.
