Holdings Maintenance Guide for Collections and Holdings in Archives
Holdings maintenance refers to the preservation activities that stabilize materials for long-term storage by placing records in appropriate housings and environments. It prolongs the useful life of an archival collection and facilitates access to the records. Sometimes called rehousing, holdings maintenance actions reduce or defer the need for conservation treatment. These actions include:
- improving housing techniques and shelving practices;
- replacing unstable and physically compromised storage materials with enclosures and boxes that meet NARA specifications;
- removing fasteners that are damaging records or interfering with access to information;
- supporting fragile records;
- reformatting unstable materials.
NARA’s Preservation Programs' holdings maintenance guidance focuses on specific formats and conditions. In addition to detailed guidance for paper-based textual records, recommendations for other media types are provided. The video Holdings Maintenance at the National Archives: An Introduction discusses basic concepts for holdings maintenance of paper-based textual records.
These pages describe best practice guidance, but common sense and archival judgment will reveal exceptions. The archival significance, condition and anticipated use of the records, as well as the space available for storing the records and the resources for the project, must be considered when planning and implementing a holdings maintenance project.
