Dewey Decimal Classification. Dewey Decimal Classification, also called Dewey Decimal System, system for organizing the contents of a library based on the division of all knowledge into 10 groups, with each group assigned 100 numbers.
Learning the Dewey Decimal System. To organize and keep track of a large collection of books, you have to have a system. Which system you use, depends on how you will need to access and use your media. Many classroom teachers organize their books by reading level or theme. In home libraries, book owners can sort by genre or even cover color. Dewey Decimal Classification is the most widely-used library system in the world. Melvil Dewey's method was first published in 1876. The system assigns a three-digit number to each book to represent its subject. Decimal points are added when further division is necessary.
