This module discusses the structure, composition, and format of various types of archival media. Agents of deterioration are covered, as well as ways to promote longevity through selecting appropriate media, understanding both controllable and less controllable factors, and ensuring proper handling and storage. Ways to minimize potential damage and information loss in an emergency or disaster are also included.
Upon completion of this module, participants will be able to:
Structure, Composition, and Formats
Structure and composition of information carriers including paper documents,
books, photographic materials, optical discs (read-only, write-once, erasable,
and DVD), magnetic disks (hard and floppy), and magnetic tapes (computer,
analog, and video).
Deterioration
Why and how archival information carriers deteriorate, including physical
damage and environmental conditions. Common deterioration problems and how
to recognize them. Remedial actions that can be taken to save information.
Longevity
Factors affecting the longevity of information carriers, including those that
are controllable (handling procedures, storage conditions, frequency of use)
and those that are not controllable (quality of the media itself, changing
technology, and obsolescence of equipment). Expected life span of various
media. How to maximize longevity.
Storage and Handling
Proper storage conditions including temperature, relative humidity, light,
pollution levels, type of storage room, and storage container. Handling procedures
to minimize physical abuse and damage including equipment maintenance, labelling
of materials, physical handling of items, and periodic winding of magnetic
tapes. Existing technical standards and recommendations by experts in the
field.
Disaster Recovery
Procedures for the recovery of archival materials from water and other disasters.
Precautions to avoid damage in the event of a disaster.
Curators, collections managers, conservators, archivists, and other personnel responsible for the preservation of archival materials.
