Well i haven't done an in-depth literature review in the past 10 minutes, no!
But here's one for starters ...
Air and Environmental Contamination Caused by COVID-19 Patients: a Multi-Center Study - PubMed
And one from our shores (again from hospitals, which contradicts the Italian study)
Detection of SARS-CoV-2 within the healthcare environment: a multicentre study conducted during the first wave of the COVID-19 outbreak in England - PubMed
By the way, Allan Bennett from PHE Porton Down (the principal author on that paper) is widely regarded in the biosafety community as being pretty much a national treasure when it comes to infection control!
I'll leave this here, but this is a pretty robust review, in my opinion
A Systematic Review of Surface Contamination, Stability, and Disinfection Data on SARS-CoV-2 (Through July 10, 2020) - PubMed
I'll be washing my hands whenever i have touched something i'm not in control of, and i advise others to do the same, especially as the new variant spreads.
It's all about reducing risk, so if you are in a shared workspace, for example, i would recommend reducing the risk to yourself by disinfecting your work area and particularly equipment before you use it. (Cue the knob gags!)
People wearing masks in a disciplined way will obviously have an impact on how much virus they plant on surfaces, but like any control measure that is dependent on people's behaviour, it is very much dependent on how well they implement it. I'd be very wary in an uncontrolled public setting.
Regarding books, even the earliest studies demonstrated that you couldn't recover the virus from paper or similar absorbent materials, so i don't think quarantining books is necessary.
Stay safe - and STAY APART!
