The International Standard Archival Authority Record (ISAAR) is a set of guidelines developed by the International Council on Archives (ICA). It provides a framework for creating authority records that help identify and describe archival entities, such as individuals, organizations, and families. This standard aims to enhance the consistency and quality of archival descriptions, making it easier for researchers to locate and understand archival materials. ISAAR promotes the use of standardized terminology and structure in archival records. By following these guidelines, archivists can ensure that their records are interoperable and accessible across different institutions and systems. This ultimately supports better research and preservation of historical documents and records related to cultural heritage.
