You can use the Law Library’s Guide to Law Online for U.S. States and Territories to locate information about state actions taken in response to the novel coronavirus.

Links to a state governor’s office and state administrative regulations can be found under the Executive header on each page while existing laws and pending state legislation can be found under the Legislative header
