Preservation and conservation

Preservation activities aim to minimise the physical and chemical deterioration of records and other artefacts, and to prevent the loss of information content (this is also known as passsive conservation). Active conservation involves remedial treatment, preserving records or other artefacts in their original format, and should be undertaken by qualified professionals.   

To maximise the life of archival records:

  • Handle carefully
  • Store in appropriate containers
  • Avoid exposure to extreme temperature and relative humidity (high temperatures accelerate the decay processes, cooler temperatures slow them down; RH levels above 65%  encourage the growth of mould and fungi)
  • Avoid exposure to fluctuations of temperature and relative humidity (these weaken the fabric of the document and are particularly damaging to multi-layered records like photographs)
  • Avoid exposure to light
  • Avoid exposure to dust and other pollutants
  • Avoid amateur repairs using sticky tape, etc.
