built 628 days ago
The Dewey Decimal System is a classification system first developed by Melvil Dewey in the 1870's. It is now the mostly widely used classification system in the world, being used by libraries in 135 countries, as well as on the World Wide Web to organize information by subject. Below is a list of the basic subject divisions of the Dewey system. Be aware that some nearby libraries use a different classification system, known as the Library of Congress (LC) system, to organize their books.

The Dewey Decimal System is a method of organizing books by grouping similar subjects into 10 main classes and assigning each a number. Each of the 10 main classes is then subdivided further. It's not always easy to pinpoint where to look just by the names of the 10 main divisions. For instance, would you think to look for a book about your new puppy (636.7) or kitten (636.8) under "TECHNOLOGY"?! Here's a breakdown of some of the things you might find in each category:

The Dewey Decimal System divides the world of knowledge into ten broad categories, starting with the numbers 0 to 9. Within those ten categories are divisions, and within the divisions are sections. The numbers after the decimal point provide even more detail. In simple terms, this means that each Dewey number represents a specific subject. Here are some examples:

The Dewey Decimal System is a way to sort books. It's usually used in public libraries and schools. It sorts the books by subject using numbers from 000 to 999. Each subject has its own set of numbers. The system was created by Melvil Dewey in 1876. It is ... called the Dewey Decimal Classification.

The Dewey Decimal System was developed by Melville Dewey. It organizes information into 10 general subject areas. Each of these main sections is further broken down into 10 subdivisions and each subdivision broken again and again into smaller more defined subheadings within the main subheading. Different topics are assigned numbers, known as "call numbers". For example, "Animals" are located in the main category 500's and the subcategory, 590. Mammals are in 599. The major categories are listed below.

In the Alvin Sherman Library, the Dewey Decimal System is used for the children's and young adult collections. Most other collections in the Alvin Sherman Library, including all other circulating books and the reference collection, use the Library of Congress Classification System. Sound recordings (compact discs and cassettes) are classified by ANSCR, the Alpha-Numeric System for Collections of Recordings.
