phased preservation

n.A preservation management technique that emphasizes actions that have the greatest impact on the preservation of collections as a whole, rather than concentrating on treating individual items.


Phased preservation includes surveys to establish priorities, disaster planning, environmental controls, and holdings maintenance.


UNESCO 2001 (phased conservation) A concept developed at the Library of Congress, originally conceived to meet the short-term needs of items that would eventually be given full conservation treatment. Surveying is an important aspect of phased treatment; items are categorized by certain characteristics or conservation problems so that they may later be retrieved for treatment.
