Archival preservation refers to the methods and practices used to protect and maintain historical documents, records, and artifacts. This process ensures that valuable materials remain accessible for future generations. Techniques include proper storage conditions, such as controlling temperature and humidity, as well as using acid-free materials to prevent deterioration. Additionally, archivists often digitize documents to create electronic copies, which can help reduce wear on original items. Preservation also involves regular assessments to identify any signs of damage, allowing for timely conservation efforts. Overall, archival preservation plays a crucial role in safeguarding cultural heritage and historical knowledge.
