books according to 10 broad classes, including computers, technology, arts, and literature. The Dewey Decimal numbers on the spines of
books are “call numbers.”The book’s Dewey number and the first three letters of the
author’s last name make up the book’s call number. Step 2. Learn the classification within the 10 main
categories, which divide books according to subject matter. For instance, the 700 class, Arts, is subdivided
into 10 divisions, including Drawing, Painting, and Music. Step 3. Consider subdivisions within subdivisions. For example, within 750, Painting, you will
find Color, Symbolism, Religion, and Human Figures. Step 4. Divide the subdivisions into sections. The subdivision of class 700, Arts, includes
the division 750, Painting, which includes 759, Historical, which comprises such sections
