There are several reasons why the library is closed on Monday: First, as a public place, the library has a large number of visitors on Saturday and Sunday, so the damaged books and equipment in the library need to be repaired, such as self-service machines and other equipment need to be repaired regularly, and some systems need to be upgraded. Then there is the requirement of hygiene. The library is a public place, and the sanitary conditions are particularly important. It is particularly important to clean the reading area and toilets on Monday and carry out large-scale cleaning and disinfection. The library is a public place, and the sanitary conditions are very important, such as toilets, which need to be cleaned and disinfected on a large scale on the day of closing. There are still some books that are not standardized and need to be returned in time. It was impossible to move books on such a large scale on Saturday and Sunday. After closing, in order to better serve readers and make them find books more conveniently, they reorganized. Librarians also need a rest after six days of work.
In a word, the library is not open to readers. In fact, it is the same reason that crosstalk also goes to work on Saturday and Sunday, and is closed on Monday or other weeks. As a special industry, the library is the reading world for readers, who are generally office workers or student parties, and only have time to study on Saturdays and Sundays.
Of course, not all libraries are closed on Mondays. In fact, the closing time of the library is set by its own library, and you can choose any day, but generally you don't choose Saturday and Sunday. There will be a day in a week to tidy up the library. As the saying goes, rest is for better work, so is closing the library.
