The REALM Project has released the results of the first round of Battelle's laboratory testing for COVID-19 on commonly circulated library materials. The five materials tested in this round included a hardback book cover (buckram cloth), paperback book cover, plain paper pages inside a book, plastic protective book covering, and a DVD case. The results can be found at https://www.oclc.org/en/news/releases/2020/20200622-coronavirus-undetectable-after-3-days.html.
The Project has also released "Systematic Literature Review of SARS-CoV-2: Spread, Environmental Attenuation, Prevention, and Decontamination," prepared by Battelle. See https://www.webjunction.org/content/dam/WebJunction/Documents/webJunction/realm/systematic-lit-review.pdf.
