1. Borrowing books should be polite, not rude.
2. Don't turn pages quickly, don't tear pages, and if the book is damaged, repair it in time.
3. Books are the ladder of human progress-Gorky.

His home is on the shelf when the book is lying. Of course, any book has its own place and that place is his home. Don't put other books where they are, but put them back where they were.
