Study Notes
Understanding Conservation and Preservation
- Conservation involves planned supervision and care of library and archival resources, protecting them from age, use, and environmental factors.
- Preservation is safeguarding items from harm, decay, or destruction, encompassing both physical materials and the information they contain.
- Techniques for preservation include reformatting, replacement, and protective containers to extend the life of documents.
Differences Between Preservation and Conservation
- Preservation supports extending access to information; conservation focuses on the physical treatment of specific items or collections.
- Conservation includes both preventive measures and intensive procedures that may require extensive time.
Key Principles of Preservation
- Identify factors contributing to the longevity of library and archive materials.
- Learn proper handling techniques for research materials.
- Develop disaster response plans and understand different storage furniture and settings.
Environmental Conditions for Preservation
- Optimal preservation requires maintaining stable humidity, temperature, air quality, and light exposure.
- A poor environment can lead to deterioration of materials, resulting in dirt, fading, mold, brittleness, or pest infestation.
Recommended Conditions
- Ideal relative humidity (RH) for storage areas is around 50%, with a consistent temperature of approximately 60°F (16°C).
- Fluctuations in temperature and humidity are detrimental to preservation efforts; consistency is crucial.
Impact of Climate on Preservation
- Heating during winter tends to dry the air excessively, risking harm to archival materials.
- Air conditioning lowers humidity, but if it is turned off during closures, RH can increase dramatically.
Understanding Relative Humidity (RH)
- Relative humidity refers to the amount of moisture in the air relative to the maximum it can hold at that temperature.
- Temperature and RH are inversely related; as air cools, RH increases, and vice versa.
- At 100% RH, the air is fully saturated with moisture, leading to precipitation in various forms (rain, condensation, etc.).
Importance of Monitoring
- Regular monitoring of temperature and humidity levels helps prevent detrimental conditions for storage materials.
- Maintaining a controlled environment not only preserves physical items but also ensures the accessibility of critical information.
