Subject	Archival description

ISAD(G) is the international standard for describing archival materials produced under the auspices of the International Council on Archives and adopted in 1994 to harmonize descriptive practices across institutions such as the Library of Congress, British Library, National Archives (United Kingdom), Bundesarchiv, and Bibliothèque nationale de France. It provides a framework that has informed the work of organizations including the International Federation of Library Associations and Institutions, the Society of American Archivists, the Australian Society of Archivists, the Archives New Zealand, and the Istituto Centrale per il Catalogo e la Documentazione. Major repositories like the National Archives and Records Administration, the Vatican Secret Archives, and the Smithsonian Institution have implemented its elements to improve interoperability among systems such as OCLC, Archivematica, AtoM (Access to Memory), and ICA-AtoM.

Overview and Purpose

ISAD(G) articulates a common set of elements for describing archival materials to support exchange among institutions such as the National Library of Australia, the Royal Archives, the State Archives of Russia, the Canadian National Archives (Library and Archives Canada), and the National Archives of Scotland. The standard aims to enable compatibility with metadata schemas used by projects like Europeana, platforms such as Digital Public Library of America, initiatives from the UNESCO Memory of the World Programme, and national catalogues including the Service Public Fédéral (Belgium). It is designed to assist archivists working in contexts like the International Criminal Court, the World Health Organization, and the United Nations Archives in producing consistent descriptions for transfer, discovery, and preservation workflows coordinated with tools from Preservica and DuraCloud.

Historical Development

Drafted by a committee of the International Council on Archives with contributors from the International Institute of Social History, the National Library of New Zealand, the Archives Nationales (France), and the Public Record Office (UK), ISAD(G) was approved at an ICA conference influenced by earlier efforts from the Society of American Archivists and the British Records Association. Its 1994 publication followed precedents in standards such as the Anglo-American Cataloguing Rules, the MARC 21 format, and the work of the International Federation of Library Associations and Institutions on authority control, while subsequent revisions responded to digital challenges highlighted by projects like Europeana Collections and the Digital Millennium Copyright Act era practices. Regional adaptations emerged in bodies including the Council of Libraries and Information Services in Canada and the European Union archival networks, shaping implementations by the National Archives of Australia and the State Archives of Finland.

Principles and Structure

ISAD(G) is organized around general principles reflected in element sets used by repositories like the National Archives (United Kingdom) and the Library and Archives Canada, and structured into areas comparable to metadata frameworks such as Dublin Core, Encoded Archival Description, and MODS. Its hierarchical approach echoes practices from the International Standard Bibliographic Description and aligns with authority control systems employed by the Getty Research Institute, the Union List of Artist Names, and the Virtual International Authority File. Key components serve institutions including the Netherlands Institute for Sound and Vision and the National Film and Sound Archive by specifying elements for provenance, custodial history, scope and content, and extent—elements that integrate with catalogues maintained by organizations like OCLC and standards bodies such as the International Organization for Standardization.

Implementation and Use in Archives

Practical application of ISAD(G) appears in archival processing workflows at the National Archives of Norway, the Israel State Archives, the Japan Center for Asian Historical Records, and the Hrvatski Državni Arhiv where metadata is ingested into systems like Archivematica, AtoM (Access to Memory), and bespoke collections management systems used by the Tate Gallery, the Metropolitan Museum of Art, and the Getty Museum. Training programs provided by the International Council on Archives, the Society of American Archivists, and university departments at University College London and the University of Toronto teach ISAD(G) alongside standards such as EAD and ISO 15489. Implementation challenges have led institutions like the National Archives of Ireland and the State Archives of Georgia (country) to develop local guidelines bridging ISAD(G) with national legislation such as the Data Protection Act 1998 and interoperability efforts with services like Europeana and the Digital Public Library of America.

Relationship to Related Standards

ISAD(G) interfaces with descriptive and technical standards including Encoded Archival Description, MARC 21, Dublin Core, EAC-CPF, Metadata Object Description Schema, and OAIS (Open Archival Information System). It has influenced and been adapted in regional schemas promoted by the Council of Europe, the European Commission, and the Organisation for Economic Co-operation and Development, while coordinating with authority files maintained by the Library of Congress Name Authority File and the Virtual International Authority File. Collaborative projects between the International Council on Archives and the International Federation of Library Associations and Institutions have sought alignment with persistent identifier initiatives such as ORCID and Linked Data efforts exemplified by the Wikidata community.

Criticisms and Revisions

Critiques from practitioners at bodies like the Society of American Archivists, the Australian Society of Archivists, and the Archivists’ Council of South Africa have pointed to ISAD(G)'s limitations for born-digital records encountered in projects at the European Organisation for Nuclear Research, the Internet Archive, and the National Archives (UK), prompting amendments and complementary guidance from the International Council on Archives and collaborations with standards organizations such as the International Organization for Standardization and the World Wide Web Consortium. Debates involving stakeholders from the National Archives of Canada, the Royal Commonwealth Society, and university archives at Harvard University and the University of Oxford have informed updates to practice, integration with EAD3 and RDF modeling, and the development of training resources by the International Council on Archives and regional partners.
