What you should ask is what the library teacher does, sorting out books, managing the silence of the library, and going through the formalities of borrowing and returning books.

A teacher in a library usually does not undertake the task of discipline, and sometimes takes the place of other teachers, depending on his or her major in school, but he or she mostly does management work in the library.

The library is the soul of a university and the most sacred place in the university. Students can do many things in the library, especially for postgraduate entrance examination, final examination and graduation.
