Preservation Department

Feb 24 - Mar 2




The mission of the UC Berkeley Library's preservation program is to maintain the collections in serviceable condition. The Preservation Department is responsible for preservation of paper and film-based collections. Digital collections are preserved by the California Digital Library on behalf of all the University of California campuses.

The Preservation Department pursues four objectives toward achieving its goal of maintaining the collections in serviceable condition:

  1. All collections are protected against catastrophic loss from disaster.
    A written disaster response and collection salvage plan is maintained by the Preservation Department to facilitate emergency salvage operations. Salvage equipment is kept on site, and a cache of supplies adequate for salvaging 100,000 volumes is maintained by the libraries of the UC system. 
  2. Damaged and deteriorated general collections' materials are repaired or replaced in order to continue to provide library service.
    The UCB collections are used 3-4 million times/year. Artifactually significant special collections are conserved and put in individual protective enclosures to minimize wear. Treatment is kept to a minimum to avoid unwanted modifications of original books and documents and to extend preservation care to as many volumes in the collection as possible with available resources. 
  3. Newly acquired materials especially vulnerable to damage or loss of parts are preserved on receipt through library binding and individual protective enclosures.
    A large percentage of the Library's preservation resources is dedicated to the library binding program in order to take full advantage of the long-term preservation benefits that accrue from preservation action taken early in the use life of collections. 
  4. Collections are maintained in environmental conditions favorable to their long-term survival.
    While the San Francisco bay area has a climate relatively benign to paper-based collections, newly constructed libraries and storage facilities include relative humidity control and air filtration to maximize the service life of the collections.

Additional goals of the Preservation Department are to contribute to the profession by participating in education and training of preservation personnel, and to the research library community through leadership in preservation work at University wide, statewide, and national levels.
