(1) Treasury fire protection device
Numerous examples of the destruction of fires in ancient Chinese library buildings have provided warnings for future generations. Therefore, in the protection of ancient books in modern libraries, fire prevention is also a top priority. In order to prevent the devastating threat caused by fire, many ancient books and treasures have been installed with smoke alarm sensors and gas fire extinguishing devices. Once there is fireworks in the warehouse, they will automatically power off and extinguish the fire. At the same time, cold light is installed in the warehouse to reduce the damage of light radiation to rare books of ancient books.
(2) Treasury moisture-proof equipment
The humid climate is very harmful to ancient books. The book library is too humid, and the book is damp and mildewed, and with proper temperature, it is easy to breed bookworms. The ancient library building is mainly protected by ventilation. Today's modern library uses constant temperature and constant humidity central air conditioning to control the temperature and humidity of the warehouse. It can control the temperature at 14 °C ~ 18 °C for many years and the humidity is controlled at 50%. 60% of the best condition to keep the ancient books from the threat of excessive temperature and humidity.
(3) Measures against insects, dust and light
The damage of locusts to ancient books is fatal, and the phenomenon of locusts in ancient books is extremely common. Some books with serious mites are so riddled that they are terrible. Therefore, pest control measures are an important aspect of ancient books protection. Before the 1990s, most of the library's anti-insect measures were to put anti-insect drugs such as camphor powder and camphor in the warehouse. However, practice has proved that although this method has a certain effect, it is not ideal because it is placed in an open bookshelf, and the use of chemicals to kill insects may also cause harm to books. In addition, in the past, the ancient books were light-proof and dust-proof, and the method of making a cover or wrapping with kraft paper was often used. After the 1990s, many libraries used the ancient books to protect the special funds, and customized the wooden box or the wooden cabinet for the good book to achieve the protection against insects, dust and light. In terms of pest control, the use of frozen insecticidal technology has begun. Anyone who has entered the library will be able to enter the warehouse after freezing, so as to prevent the eggs from being brought into the warehouse with the book. The freezing method has a good insecticidal effect, but the cost is high, and most libraries have not yet adopted it. Practice has proved that the humidity of the warehouse is above 70% and the temperature is above 22 °C, which is the best environment for aphid reproduction. For this reason, the best insect control method is to control the temperature and humidity conditions for the growth of bookworms.
(4) Treasury anti-theft monitoring equipment
In recent years, the phenomenon of the theft of ancient books in the library has occurred both at home and abroad. It is still an indispensable measure to install security doors in some libraries' warehouses, set up special personnel to keep them, and count the collections of the houses every year.
(5) Strictly implement the management system of the warehouse
The key to the effectiveness of the protection of ancient books is the formulation and implementation of the management system. In order to protect the safety of key rare books, the library has established duties such as the good book entry and exit system, the personnel entry and exit system, and the working rules of the warehouse staff, and the possible omissions are controlled in the bud.
(6) Inheriting and carrying forward the traditional key repair skills
The modern facilities of the library can improve key preservation conditions, but they cannot solve the regeneration of damaged ancient books. The repair of damaged ancient books is still an important part of the protection of ancient books in the library. Over the years, after the manual labor of the repaired personnel, a large number of severely damaged ancient books have been rescued, restored to their original appearance, and achieved the role of renewing the ancient books. In terms of repair methods, the library has developed a pulp repair technology (Nanjing University) and invented the pulp filling machine (National Library). In order to summarize the inheritance skills of the predecessors, and to increase the experience to the theory, the "Chinese ancient book binding and repairing technology", "Remediation and binding of ancient books" written by experienced national restoration personnel has been published, marking the specialization of ancient restoration techniques. Standardized, a group of ancient books repair experts have emerged.
The history books and ancient books scanned by the production books and magazines are an important task for libraries, archives and museums.
