REopening Archives, Libraries, and Museums (REALM) is a research project conducted by OCLC, the Institute of Museum and Library Services, and Battelle to produce science-based information about how materials can be handled to mitigate COVID-19 exposure to staff and visitors of archives, libraries, and museums. The studies are conducted by applying the virulent SARS-CoV-2 virus on five materials (per test set) held at standard room temperature (68°F to 75°F) and relative humidity conditions (30 to 50 percent). Below are the results of tests completed to date.

REopening Archives, Libraries, and Museums (REALM) is a research project conducted by OCLC, the Institute of Museum and Library Services, and Battelle to produce science-based information about how materials can be handled to mitigate COVID-19 exposure to staff and visitors of archives, libraries, and museums. The studies are conducted by applying the virulent SARS-CoV-2 virus on five materials (per test set) held at standard room temperature (68°F to 75°F) and relative humidity conditions (30 to 50 percent). Below are the results of tests completed to date.
