1, minimum intervention principle
In the restoration of ancient books, the traditional methods of whole volume mounting and leaf mounting are abandoned, and the damage status of each part of the document is analyzed in detail, and different situations are treated. Try to add less restoration materials to the collection, avoid protective damage caused by excessive restoration, and try to keep all kinds of research information of ancient books and documents.
2, the whole old as the old principle
In the restoration, the original appearance of ancient books and documents should be kept as much as possible, and the binding style of documents should be preserved. The so-called "keeping the old as the old" here is not an attempt to restore the original appearance of the document without destruction, "like the ancient" old ". It is impossible to restore the "old" in ancient times, but to keep the original appearance of the document as much as possible, that is, only the damaged part of the document will be preserved in the restoration work, and the existing situation of other parts will never change in any form.
3. The principle of reversibility
In other words, the repair measures are reversible and repeatable. If a more scientific and suitable protection and restoration technology is found in the future, the restoration materials can be replaced at any time and restored to the original state before restoration. At the same time, the principle of reversibility is very necessary for us to correct mistakes in our work and not damage ancient books as much as possible.
4. The principle of retaining historical information to the maximum extent.
That is, repair materials (paper, thread, pigment, ink, etc.). What is used in the restoration must have a certain color difference with the materials in the original literature to avoid being confused with the historical information inherent in the collection itself.
Extended data
Matters needing attention in the selection of paper for the restoration of ancient books;
When choosing the paper to repair ancient books, we should first pay attention to the pH value of the paper, and we should not use acidic paper to repair ancient books, so as not to cause or accelerate the acidification of ancient books. Secondly, if you use old paper to repair ancient books, you should pay attention to the fact that the paper strength of old paper should not be too low.
At the same time, it should be noted that the fiber composition of the selected paper should be similar to that of ancient books, with similar thickness and color, but not the same. Sticker paper has strong water absorption and easy adhesion, and the width of paper curtain pattern should be similar.
In the specific repair work, we should also pay attention to the direction of the curtain pattern of the paper and the curtain pattern of the ancient books. In short, these are all suitable, so that the paper under repair and the original leaves can be bonded firmly and harmoniously.
