Each main class is divided into ten divisions, also numbered 0 to 9, giving the second figure of a book’s classification number, and, within the main classes, books are grouped on the shelves to correspond. For instance, books on art and recreation are arranged in the following divisions:

710 Landscape
760 Engraving
720 Architecture
770 Photography
730 Sculpture
