How are historical documents digitised?

Historical documents are digitised using specialised techniques to preserve their integrity while creating high-quality digital replicas. First, the documents are carefully prepared by removing any bindings, staples, or contaminants that might damage the scanning equipment. High-resolution scanners, often with flatbed or planetary scanning capabilities, are used to capture detailed images of each page. Given their fragile nature, historical documents may require gentle handling and specialised supports during scanning. Post-scanning, the digital images undergo processing to enhance readability and may involve colour correction and contrast adjustments. Finally, the documents are often tagged with metadata to aid in their future retrieval and study.
