Legal Analysis: Borrowing books from university libraries is still a serious problem. First of all, there will be records at the end of college, so don't take any chances. Don't feel as if no one has urged us to return the book for two or three years. This problem has passed, but it is not. After borrowing books, many universities generally limit the return period to one to three months, of course, winter and summer vacations are not counted. When we borrow books, if we don't return them within the time limit, there will be corresponding punishment. One is a direct fine. When we borrow books, we borrow books from the library through a card, and then register some cartoons. When we want to return books, but the deadline is too long, we usually need to spend a few dollars a month in fines. Some are echelon-style, that is, the longer the arrears, the more fines will be paid next month than last month. So if you add this up, if you borrowed this book in the 1 semester just after your freshman year, and then returned it when you graduated from your senior year, the money that needs to be fined may be very huge. Maybe the original price of a book is more than ten yuan, and finally you need to pay a fine of several hundred yuan, which is not worth the candle.
