So glad to see this! I hope this turns into a movement for all Americans to have the option to vote by mail. I was astounded to recently learn that it isn't currently the case. I hope this virus will become the impetus for this change.
It's been snowing on and off all day here, and I'm in California.
I agree with all the others about what a kind thing you are doing.
Yes, research the timespan CV can survive on paper (pages) and plastic (Brodart coatings and audiobook/dvd cases) and yes wipe the books down when you retrieve them, but then quarantine them for a week or two before putting them on the shelf. At least that's what makes sense to me.
I too am staff in a tiny library, and while my county doesn't have any cases yet, I'm sure it's just a matter of time. I wonder if my county library will direct my branch to close when that happens. If so I might take inspiration from you.
