Abstract: Public health anxiety caused by media reports of the 2019 novel coronavirus is now widespread
in the USA, and misinformation can lead to discrimination against Chinese and Chinese Americans.
Therefore, access to authoritative and trusted information about the virus and general infectious diseases is
more important than ever. Using keywords of “Novel coronavirus” and “Library” and conducting search
in Google, the author analyzed the content of the websites of U.S. national libraries, state and regional
public libraries, and academic and university libraries appeared on the first few pages of the Google results
page regarding the themes of the 2019 novel coronavirus. The author sorted out and summarized the
content and suggested resources of the web pages created on the theme of the 2019 novel coronavirus
and tried to answer the following questions: What should public libraries and librarians know about the
2019 novel coronavirus? Faced with the 2019 novel coronavirus, what are the US national special libraries
doing? What resources and services do state and regional public libraries provide? How do academic
libraries and university libraries face the challenge of the 2019 novel coronavirus? The analysis results
show that libraries at all levels play different roles. The libraries not only play the role of disseminating
authoritative and reliable trusted knowledge and information, but also play the role of an educator, educate
the public to learn common knowledge and even professional knowledge of public health, and provides
corresponding consulting services and emergency services to educate the public and relieve unnecessary
panic.

Key words: 2019 Novel coronavirus, Library, Emergency services, Novel coronavirus pneumonia
