Abstract:A severe strike of the COVID-19 virus has posed a great threat to China and the rest part of the world, which also forced libraries to face the challenges and reflect on their works. In view of the current situation of public health and epidemic prevention in libraries, this paper identifies weaknesses in architectural design, spatial planning, distribution of public facilities, management consciousness and measures. The paper suggests raising the awareness of library management, make full use of information resources, invest more in library construction and improve working efficiency. It is hoped that the work of epidemic prevention in public space can be more standardized and exercised in daily life. That is how libraries can be more capable of responding to public health emergencies and be more modernized.
