Challenges and strategies in the preservation of historical and audiovisual archives

Resumo

The conservation of historical and audiovisual archives is essential for preserving cultural heritage, collective memory, and national identity. These archives—comprising documents, photographs, films, videos, and other materials—serve as critical records of historical events, cultural traditions, and social practices. However, preserving such materials is fraught with challenges, including physical and chemical degradation caused by factors like humidity, temperature, light, and improper handling. Moreover, technological obsolescence poses a significant risk to digital media. To address these issues, conservation efforts must include both the restoration of damaged materials and preventive measures to mitigate future deterioration. This involves not only restoring old photographs and repairing films but also digitizing documents and creating controlled storage environments. Digital conservation, including the migration of obsolete formats to current technologies, is crucial for the longevity of audiovisual materials. Studies highlight various challenges faced in audiovisual preservation. Rasaki et al. (2023) identified obstacles such as technological obsolescence, inadequate storage conditions, lack of funding, insufficient management commitment, and a shortage of trained personnel in a Nigerian university library. Muhammad (2019) further pointed out systemic issues, including the absence of a national preservation policy and undervaluation of audiovisual materials. Evens and Hauttekeete (2011) discussed challenges in digital preservation, noting that underdeveloped policies leave archives vulnerable to deterioration and technological obsolescence. Baker (2021) documented a significant upgrade at the University of Kansas Libraries, showcasing the expansion of conservation facilities and the creation of specialized spaces for audiovisual preservation. Effective preservation requires a collective effort that includes governments, cultural institutions, and public education. Comprehensive preventive measures—such as managing environmental conditions, regulating light exposure, and protecting collections from pollutants and threats—are essential to ensure the accessibility and preservation of valuable cultural heritage for future generations.
