People often use the terms “preservation and
“conservation” interchangeably to convey the same meaning. If you look up these terms in a dictionary
you will probably see that one is provided as a synonym of the other. They both
fundamentally mean the act of preventing decay.
In the museum and archives community, however, preservation and
conservation are two very different processes.
The Smithsonian Institute defines preservation as,
“the systematic application of principles that prolong the life of all
collections materials—analog and digital”.2 Monitoring the
conditions in which records are kept in is one of the ways in which archivists
can preserve records before they need to be repaired by professional
conservators. Conservation, on the other hand, primarily focuses on
fixing individual materials that have been damaged over time, by natural
disaster, or by accident. And while conservation often focuses on a single item,
preservation takes into account the conditions of the entire archive by
controlling things like temperature, humidity, and way in which the records are
housed. Finally, conservation is typically much more expensive.
In preservation, first and foremost is the proper
handling of archival materials - such as wearing gloves when handling
photographs. The second most important practice for archival preservation is
the control of the climate within the archives. According to the National
Archives to preserve documents and photographic materials conditions need to be
maintained at around 650 between 35% and 45% relative humidity.1
This slows the aging process and keeps mold from forming. No one likes mold.
But where do you go to get your materials put back
together? For institutions in the north-eastern United States, the answer is
the conservation department at the Winterthur Museum here in Delaware.
Winterthur was established by Henry Algernon du Pont in the early 20th
century to be both a home and a museum and today it houses one of the most
prestigious institutions for conservation learning in the country.3
And on November 4th we at the Delaware State University Archives will take a
special tour of Winterthur. But you’ll have to read about that in the next blog
post.
