The explanation of the library in the dictionary is an organization that collects, arranges and collects books and materials for people's reading and reference. The library has the functions of preserving human cultural heritage, developing information resources and participating in social education. Among them, collecting books for people's reading and reference
as to spread culture, should be the focus. This is commonly recognized by the world. However, from different angles, some people also questioned the function of the library. Ikeya izov, a famous Japanese ancient book collector, wrote in his book Hand Drawn Travel of Japanese Bookstores that the classical books purchased by the library are labeled and collected at the bottom of the box. It doesn't see the sun, and they rarely have the opportunity to appear in front of ordinary people. The library can be said to be a black hole of books.
The ancient books kept in the library are difficult to be read by ordinary readers.
