The photo and article linked above shows how clean the Suffolk libraries are getting.
One librarian goes in to deal with returns and to check on things. The deep cleaners go in to make sure that the library is ready when patrons are able to go back.
The librarian found that the deep cleaners cleaned the books all right. And sorted them by size. Perfect!
The returning librarians will have a lot of work on their hands putting every book back in its place. At least they know everything was cleaned.
