Chinese ancient books have a long history. If they are improperly preserved in the process of circulation, they will be damaged. In serious cases, there will be problems such as adhesion, embrittlement and flocculation. Some ancient books with serious damage are like “puff pastry”. . Through the hands of the ancient restorationists, the ancient books "process the disease", ranging from a few weeks to several months, some ancient books can be restored to a clean and tidy appearance, so that the life of ancient books can be continued and the classics can last forever.

In June last year, at the National Library's four-month “Special Exhibition of National Precious Ancient Books”, many restoration works of precious ancient books were also exhibited together. In the "Tianlu Linyi" restoration results display cabinet, the original book after the repair of the forty-second volume of the Six Selected Works and the photos before the restoration are displayed. By comparison, it can be found that the surface of the books before the restoration was moldy, wrinkled, and very worn, and the restored books were clean and flat.

The restoration of ancient books begins with the protection of ancient books. The digitization of existing ancient books requires the repair of ancient books and scanners. The book2net non-contact ancient books have professional scanning lenses. The matrix ccd point-to-point scanning imaging is very clear and will not be against ancient books. The quality of the written damage, this is the most important point using the LED cold light source 0 radiation also ensures that the operator works in a non-radiative environment. The non-contact ancient book scanner can scan any book that has been booked and does not need to be opened.

Repair ancient books:

The first step in protecting ancient books is to decompose and dismantle ancient books. There are three main methods: drying with bamboo-made screwdrivers, moistening ancient books with water, and then exposing the ancient books. The method adopted by Zhu Zhenbin to repair the "Dan Yuan Ji" is "steaming." "Giving papers and wrapping towels on ancient books to prevent direct impact of steam, softening the parts of the pages that are stuck by heat." Zhu Zhenbin said that "Dan Yuan Ji" has a book of more than 100 pages. After steaming, it will open several pages. When the book bricks are dry, it will be repeatedly steamed and repeatedly exposed. In the three months of repairing, it takes about one month for steaming.

After the book was dismantled, most of the time was used to “break up”. "Northern worms are straight up and down, and the southern worms are generally turning and bending." Facing the wormholes on the pages of ancient books, Zhu Zhenbin told reporters that the method of filling holes used "micro-phase". Technology, the torn paper fiber will be smudged with the edge of the ancient book bite. Which is the best way to solve the damage problem with the least repair material, can not directly carry a piece of paper on the back, "support the paper, the whole The book is thick, the appearance has changed, and it violates the principle of minimum intervention and old-fashioned." Zhu Zhenbin said, like "Dunhuang suicide note", there are written information behind some books, and you can't see it after loading the repair paper. The curtains of the base paper are also blocked, which makes it difficult for people who may study ancient papers in the future, so try to stay as they are.
