Archival bond

The archival bond is a concept in archival theory referring to the relationship that each archival record has with the other records produced as part of the same transaction or activity and located within the same grouping. These bonds are an core component of each individual record and are necessary for transforming a document into a record, as a document will only acquire meaning (and become a record) through its interrelationships with other records.

The concept of the archival bond is primarily associated with the work of Luciana Duranti, who first proposed the concept, along with Heather MacNeil, as part of research into the integrity of electronic records
