Eternal preservation through digitization


MLA collections include ancient books, manuscripts, artwork, photographs, and film that are precious cultural heritages that must be preserved for future generations. However, the utmost care and attention taken in the preservation of collections cannot always eliminate the effects of aging brought on by the advancement of time which could make some collections inaccessible in the future. Pre-emptively digitizing collections ensures long term preservation and backup of the contents in the event that originals become inaccessible for any reason, and provides various opportunities for using digitized data.

The Vatican Apostolic Library is conducting a digitization project in order to create a digital archive with a view to handing on these precious handwritten materials to future generations as an eternal cultural legacy. NTT DATA Corporation has agreed to participate in this Vatican Apostolic Library digitization project, an endeavor that can be considered a major contribution to humanity. In April 2014, NTT DATA began working on the project, with plans to digitize approximately 3,000 handwritten manuscripts over the course of the next four years. Since most of the manuscripts are written on fragile material such as papyrus, they are carefully scanned using specialized equipment followed by adding metadata such as author and keywords, and finally the data is stored in a data center located in Vatican City State. Currently, these digitized collections are partially open to the public online in order to enable visitors search and view them.




Tens of thousands of images and half a million indexed data of the Akita Prefectural Library as well as documents owned by six external institutions including museums, public record offices, and art galleries have been digitized, cross indexed, and made searchable. Each institution originally had used different cataloguing formats, however this complication has been resolved by unifying them using the AMLAD mapping feature, thus powering Discovery Service. The digitized data has been linked to the National Diet Library, to effectively share electronic information and to function as a community hub especially for elderly and young families.
