REALM Project update: Test 4 Underway Five items were selected for the fourth round of Battelle lab testing to examine the length of time the COVID-19 virus may live on materials commonly used in archives, libraries, and museums. The study began on Friday, July 31, on items provided by Columbus Metropolitan Library and the National Archives and Records Administration. In response to feedback from the library community and discussion among REALM working groups, four of the five items selected for test 4 are similar book materials as were studied in test 1; for this test they will be stacked to simulate their common storage configuration in bins, book drops, and on shelves.
