In any case, paper books are irreplaceable. When reading paper books, you can touch the pages with your hands and smell the ink, which is a sense of sureness that e-books can't replace. More importantly, there are so many books in the library that we can't download all the books online, and we can't afford to buy all the books. Therefore, the existence of the library must be meaningful and irreplaceable. At the same time, people who go to the library more often must be people who like reading. There, they can meet like-minded people, make more friends and learn more. Therefore, even in the information age, the library is still an indispensable part of our life.
