Late last week, School Library Journal released an article titled "IMLS, CDC Offer Guidance for Disinfecting Returned Library Books." It's largely a summary of the IMLS webinar from March 30 about managing paper-based circulating collections (recording available online). However, the article includes a link to a study publishe​d in the Lancet that I had missed which includes this reassuring information: "No infectious virus could be recovered from printing and tissue papers after a 3-hour incubation​."​

See the SLJ article for more detail and recommendations for handling library materials.
