Our collective knowledge of SARS-CoV-2, the virus that causes COVID-19, continues to evolve as researchers across the world work to understand and combat the virus. In such an uncertain information landscape, establishing best practices isn’t easy; it requires library workers to balance community needs with the best available guidelines for limiting the virus’s spread. Since May, the REopening Archives, Libraries, and Museums (REALM) project—an Institute of Museum and Library Services (IMLS)–funded collaboration between OCLC and the research and development organization Battelle—has been studying surface transmission risks of common library and museum materials. Results from the first five rounds of tests, illustrated in this infographic, show that the virus’s survival time varies widely.
