People often compare the library to a treasure house of knowledge, which contains profound cultural connotations. When we step into the library, we will feel that it is so profound, so profound and magical, so charming. In school, the library is the second classroom for students to learn, an important position for quality education, an effective way to broaden students' horizons, cultivate their sentiment, cultivate their aesthetic taste and acquire knowledge, and a base for students to grow into talents. It provides students with a rich spiritual and cultural feast, creates a good campus cultural environment, subtly cultivates students' culture and exerts its educational function.

However, in some local primary and secondary schools, the construction of libraries is seriously lagging behind, and the collection of books in libraries is far from meeting the reading needs of students, and even many books in them are not suitable for students to read. First, there are many outdated books. For example, in some schools, in order to make up the number of books and survive, books can meet the standards set by superiors. The library is full of outdated and neglected popular science literacy books and other books suitable for adults to read many years ago, but they still dare not rush out to make up the numbers. Second, the library has a small number of books and a single type, which makes it difficult to attract students' eyes for knowledge. Under the baton of "exam-oriented education", even if schools have money to buy new books, they often give priority to supplementary books, while literature, art and natural science cultivate students' comprehensive quality and improve their ability, and students want to borrow and read few books.
