Some people may say that you can write and draw in the sidebar of the book, and you can even draw or trace lines under words and phrases. But if you want to keep this book, put it in the library or sell it-don't write anything on it. Ink will do permanent damage to your book. Write things in a diary or notebook, or use small pieces of paper, which is easy to paste and so on. If you must write, you'd better use a pencil and erase it afterwards.
Step 2 stay away from food and drinks
Food and drink are extremely dangerous for your book. The best way is to read without eating or drinking, and make sure your fingertips are clean and dry when turning pages. At the same time, keep books away from food and drinks. Make sure that there is no water, crumbs and sticky objects on the table (or other surface) before putting the book on it.
Use carefully.
Be careful with books, and don't bend the corners of books when reading (use bookmarks instead). Don't break the back cover. Do not damage the spine; Don't turn the book upside down. Cover the book and keep it intact.
Put it on the shelf
If you want to take care of books, put them on the shelf when you are not reading. But at the same time, we should also pay attention to whether the books are placed correctly. Every book must be placed face-to-face (not sideways, let alone piled together). Every book should have enough upper space (space above the book) so that it won't touch the spine when you put the book. If there is no room for the bookshelf, put your books in the box-keep them upright.
5. Waterproofing and heat insulation
When placing bookshelves, put them in a dry place-there is no direct sunlight and no heat source. If you put the book in a damp place (such as cellar, bathroom or other damp places), it will grow mold. Sunlight will damage the spine of the book. Moreover, overheating will make books dry and paper fall off.
6. Stay away from insects, pets and other livestock.
Worms and mice can bite books, and dogs can eat books; The cat tried to grab the spine of the book. Putting books in a clean place (cover) can avoid many such problems. If possible, it's also good to close the library door (in case cats and dogs accidentally break in). In addition, keeping books away from food will reduce their attraction to mice and other livestock (although sometimes mice eat books to build nests), and there should be no dust particles near books.
7. Please keep it out of the reach of children.
It is important to encourage children to study, and it is also important for them to see that you are studying. However, children will also tear books and bite them, destroying your most precious books together with the previous factors. You can teach your children to use books carefully according to their age. If they are too young (or impatient), this trick won't work: then close the library door, put books on shelves that are hard to get, or buy a bookcase that can be locked. Also, this is not to stop children from reading, but to protect books.
