At SEK Library Media Center, we use the Dewey Decimal Classification system (DDC) to arrange books on similar subjects together. This classification system was invented in 1876 by Melvil Dewey. It is kept up to date and is widely used around the world in all types of libraries. Dewey organised all of the world's knowledge into ten great divisions - hence decimal.
