Library LOLs

One of the Circ workers left a book on the mending shelf that was thoroughly soaked with water and reeking of mildew, and stuck to it was a note saying that the patron who returned it claimed it was like that when they checked it out.

Random thoughts I've had lately about books:
1. Why do book printers make books so tall and so wide that they won't fit on a standard bookshelf?
2. Why are some books constructed without spine cloth?
3. If everyone who has a borrowed library book in their possession right now returned those books all at once, how screwed would the Libraries be for space?
