1. Anti-aging. The aging and brittleness of books does not depend on the length of time, but on how to deal with the acidic substances contained in the pages. It has been found that some of the books published in Europe in the 15th century have survived to this day because the paper was made of cotton and linen heads, had a neutral pH, and contained calcium carbonate, which prevents acid formation.
In modern society, the circulation of books is very large, and it is obviously impossible to make paper from cotton and linen, so most of them use wood as raw material. The plant fibers in the paper lose their strength and adhesion when hydrolyzed by acid, and the acid in the paper mainly comes from the aluminum sulfate that sizes the paper. When the paper starts to get wet, the aluminium sulphate begins to produce sulphate and hydronium ions, and finally forms an acidic substance that erodes the paper.
Sulphur oxide and cyanide oxide in polluted air can also react with water or plant fibers to produce acids. Therefore, to prevent books from aging and becoming brittle, the main thing is to remove the acid in the paper. The most common method now is to soak the book in a solution of magnesium bicarbonate or calcium bicarbonate and then dry it.
By doing so, you can get the acid in the paper and prevent the acid reaction from happening later. 2. Insect control. Sometimes small insects grow on books, which seriously jeopardizes the lifespan of books.
The methods to prevent insects are: 1. The articles in the collection should be clean and dry, and well ventilated; There should be no cracks in the bookshelves, walls, or floors; 2. The temperature of the collection of books and articles should always be kept at 6-20 degrees, and the humidity should be kept between 50% and 60%; 3. The collected books should be moved frequently, even if they are not commonly used, they should be turned regularly; 4. On the bookshelf or in the bookcase, you can put some wrapped sanitary balls. 3. Decontamination.
Stained books will not only shorten the life of the book, but also affect the effect of reading. The methods of decontamination are: 1. Remove grease stains.
Put a piece of absorbent paper on the oil stain and gently iron it several times with an iron to absorb the oil. It can also be erased with a few drops of a mixture of gasoline and magnesium oxide. 2. Ink removal.
At the bottom of the page stained with ink, first pad a sheet of absorbent paper, then soak the stain with 20% hydrogen peroxide solution or potassium permanganate solution, then put a piece of absorbent paper on the top of the page, and press a heavy object, and the ink will disappear after drying. If brown spots occur with a potassium permanganese solution, they can be removed with oxalic acid or citric acid solution. 3. Remove mildew.
Dip cotton in ammonia and gently rub the mold until it is removed. 4. Remove finger prints. Rub your fingerprints with soap, then wipe off the soap with a damp cloth, and finally line the pages with absorbent paper to blot the water.
5. Remove fly feces. Dip cotton in vinegar or alcohol and gently rub fly stool until the stain is removed. For other general stains, as long as you carefully wipe it with soap, then wipe off the soap with a damp cloth, and then line the book with absorbent paper to absorb the water, you can get a more satisfactory effect.

I manage my collection in the most stupid way – my resume excel.
1. Classification: There are three tables to roughly divide the collection and search for it.
1. The first table is [Book Series], which is used to save your favorite books and prepare to collect a complete set or part of the series, such as Sanlian's "Chinese Translation of World Academic Classics", Business's "Chinese Translation of World Academic Classics Series", Zhonghua Book Company's "Science Series", "New Zhuzi Collection", "Historical Notes of Past Dynasties Series", "Notes of Past Dynasties" and so on.
According to the following bibliography of the series, fill in the details of those who have been purchased, and those who have not purchased and are ready to buy are highlighted with a yellow background.
2. The second table is [Set of Books], which mainly preserves anthologies and collections, such as Nan Huaijin Anthology, Qian Mu Anthology, Huang Renyu Anthology, etc., which are classified by person, and the following is a bibliography.
3. The third table is [Scattered Books], which is used to preserve scattered books that are not in a series, and which are classified according to famous works, **, history, prose, poetry, etc., and the following is listed in the bibliography.
2. List: Each book mainly includes the serial number, title, translator, volume (volume) number, publisher, pricing, purchase date and other information, according to personal preferences, you can also add the number of editions, the number of words, the number of pages, the place of purchase, the purchase of ** and other information.
If I didn't manage the collection before, I know that doing this work all at once would be a lot of work. But finding a time, getting this work done, and adding new books every time you buy them in the future is a one-and-done method.
I don't buy heavy books, and it's convenient to find books by myself, so I don't have to climb the bookcase.

Eradicating Mandarin is the best way to preserve the dialect.
In modern enterprise management, an important task is to fully mobilize the enthusiasm of employees, that is, employee incentives. The higher the level of employee motivation, the stronger the degree of effort and satisfaction of employees to achieve the organization's goals, and the higher the work efficiency achieved. Conversely, the lower the level of motivation, the less motivation to accomplish the organization's goals, and the lower the work efficiency. >>>More
