According to the University of Illinois at Urbana-Champaign, the large-scale ancient books digitization project initiated by the school has achieved remarkable results. In addition to the digitized text, the full text can be retrieved, and the original books in the collection are also well rescued, and the damaged books have been repaired and saved.
Jennifer Hain Teper, director of the school's library system, said that when packaging ancient books for digital scanning, it was just the opportunity to pick out damaged ancient books for repair. This work is funded by student library fees.
Teper and Emily Shaw, who coordinates the school's work with Google's book protection, conducted a survey in advance, selected the unique collections of the school library, and then determined the ratio of books to be scanned. In addition to the books published before 1820 and the large sections of the special collections of the school library, they selected samples from ancient books to estimate their adhesion, paper embrittlement and other indicators. Based on this, the reasonable budget required for the staffing, outsourcing to the commercial binding office, and more detailed internal repairs is calculated, and large-scale digitization is prepared. All findings were published in the journal Library and Institutions published by Johns Hopkins University Press.
“The University of Illinois at the Abners Champaign Library has participated in several large-scale digital projects, such as Google Books, which is a cautious digital project,†Teper said. “However, both binding and paper strength must be able to withstand scanning.â€
There are many factors that cause books to break. The paper used in most books published after the industrial revolution and in the 20th century is wood pulp paper containing a lot of impurities, which are easy to cause paper embrittlement. At the same time, these books are also bound with adhesives, so the breakage rate is faster than the manual sewing of the stapled paper. Teper and Shaw will focus on making sure the books are intact before digitizing, lest they become brittle or stapled during scanning.
Teper said, “Now the ancient papers are close to fragile conditions and can be digitized by high-quality scanning. Once these books become fragile, they are no longer suitable for large-scale digital engineering.â€
Many of the books in the Google Books project are classified as "medium rare" and are not a rare special category, but perhaps pay attention to the problem of scan damage. For example, the book published in the Victorian era is a hardcover cloth. According to Teper and Shaw, these files have not only textual value but also cultural heritage values.
The DSC Universal Image Acquisition System produces the highest quality products available at the current state of the art and is suitable for a wide range of materials. The DSC Universal Image Acquisition System handles manuscripts ranging from historical stamps and coins, film and glass negatives to large-format precious books and calligraphy, and even textiles, wood, stone and metal. The system can be applied to digital projects in archives, libraries, museums, art galleries, land surveying, building materials decoration, printing and publishing, art simulation and other industries. At the same time, the shutter speed is extremely fast, and the scan cycle is extremely short, which improves work efficiency.
