The REALM project has published the results of the fourth round of Battelle’s laboratory testing for COVID-19 on five materials common to archives, libraries, and museums.

Four of the five items—hardcover book cover, softcover book cover, plastic protective cover, and DVD case—were part of Test 1, but in this round, the materials were stacked to simulate storage in a book drop, bin, or on shelves.

The fifth item, expanded polyethylene foam—commonly used in museum exhibits, storage, and shipping—was tested unstacked.
