TS ISO 11799

TS ISO 11799 is an information and documentation standard focused on how repositories for the long-term storage of archive and library materials should be planned, located, and equipped. It addresses the storage facility as a whole, including the installations and equipment used inside and around the building, because these features shape the preservation environment over time.

The standard applies to archive and library holdings that may include paper-based materials as well as mixed media stored together. It also allows for separate areas or compartments within a repository where environmental conditions can be controlled for the needs of specific archival materials, reflecting a common preservation principle: different media and object types may benefit from different storage conditions.

Why repository design matters

In general technical terms, archival and library materials are sensitive to fluctuations in temperature and humidity, light exposure, pollutants, fire, pests, and water ingress. Repository design is therefore not just a building issue; it is part of collection care and risk reduction. Well-considered storage provision supports stable conditions, safe handling, orderly access, and maintainability across the life of the collection.
