Book
A sheet of paper flat on which several pages of the same work are printed in the order where they must be read, after folding is called a book.
The etymology of this word comes from Latin Quaterni who wants to say four, because in the beginning, the books had four pages.
A sheet flat gives the broadsheet = a layer 2 pages.
folded into two 1° fold gives folio = two layers 4 pages.
folded into two 2° fold gives quarto = four layers 8 pages.

After Pliure the books can be inserted for a puncture with horse on the fold with fastened wire (booklet, weekly magazine).
The superimposed books are bent under binding with vegetable wire (delivers, Dictionnaire).
