I work in a public library. While this is fucked up and crazy, I wouldn’t worry about it too much. Librarians do not fuck around and most libraries have very similar strict and thorough rules for how they take books under review books that are extremely difficult for people to fuck with.
For example, at my library if you want to have a book be reviewed to be possibly taken off the shelf, you have to have read it in its entirety. No exceptions. They will literally quiz you on it.
