ISAD, or the International Standard Archival Description, is a set of guidelines designed to help archivists create consistent and clear descriptions of archival materials. It provides a framework for organizing information about records, making it easier for researchers to find and understand the context of the materials they are studying. The standard is widely used in the field of archival science and is essential for maintaining the integrity of archives. By following ISAD, institutions can ensure that their collections are accessible and that users can effectively navigate the wealth of information contained within historical documents.
