Digital archives refer to collections of digitized materials, such as documents, photographs, videos, and other media, that are stored and accessible online or on digital storage devices. These archives preserve cultural heritage, historical records, and academic research in a digital format, making them easily accessible to researchers, scholars, and the general public. Digital archives also allow for the storage, organization, and retrieval of vast amounts of information in a more efficient and cost-effective manner compared to traditional paper-based archives. Researchers in this area focus on developing methods for digitizing, preserving, and providing access to digital collections, as well as ensuring their long-term sustainability and usability.
