The cost and risk have increased several times, but the funds have not increased, so colleges and universities are equivalent to doing charity, sacrificing the resources that should be provided to teachers, students and employees of our school.

Outsiders can go to public libraries.

Public libraries are funded by government grants at all levels and social donations. Therefore, the development of public libraries depends on the local economic development level and the amount of government funding. The funds of university libraries come from school financial allocations and social donations. According to the relevant regulations, the cost of purchasing documents and materials should account for 5% of the whole school's education funds, so university libraries can usually maintain continuous development.

The function of public library is to serve all citizens, and the clients are treated equally regardless of their status. The function of university library is to serve education and scientific research, and the service object is the teachers and students of the school.

Public libraries also required a deposit more than ten years ago, and it took more than ten yuan to get an annual card to enter the reading room. Now it can be completely free and free of deposit, because the government has invested more than one billion yuan to pay for the people of the whole country.
