A rather common book, which contains the telephone numbers of the people in the local area and whose editions can be found in many houses around the globe. The author of the book is never a creative man, and so the plot is rather boring. The fact most of the phone numbers in the area are changed a day after the book is published gives us the reason that the common use is as a door stop, paper weight, or a low chair. Indeed a useful tool needed at every house.
