Melvil Dewey, the creator of the famous Dewey Decimal System that classifies mostly non-fiction books and library resources, was born on December 10, 1851 in New York and this date has been adopted to celebrate and honor him annually for System Day. Decimal Dewey. .

Dewey created his proprietary library resource classification system while working in the Amherst College library at the age of 21. The Dewey Decimal System was first published in 1876 and is now the most widely used system worldwide in more than 200,000 libraries in 135 countries. The twentieth edition of the system was published in the late twentieth century.


The system allows us to locate resources by topic assigned to one of the 10 classes. The top 10 groups are 000–099, General Works; 100-199, philosophy and psychology; 200-299, religion; 300–399, social studies; 400–499, language; 500–599, science and math; 600–699, technology; 700–799, the arts; 800–899, literature and rhetoric; and 900–999, history, biography, and geography.

Each class is further classified into 10 hierarchical divisions which are then subcategorized into 10 sections. The Dewey system numerical classification provides an abbreviated location and identification tool. The notation lends itself to memory through constant repetition of a standard pattern (arrangement of areas, different numbers for particular languages) through parallel subject developments, and repetition of standard subdivision patterns, such as theory, history, geography, etc.

It is hard to believe that more than 100 years have passed since the original introduction of the Dewey decimal system. Today, Americans review an average of 7 items from their local libraries each year, so the need for order continues. The digital age made obsolete the beautiful card catalog cabinets that contained the index cards with the decimal classification. Interestingly, Dewey also helped create the chips themselves. The same year that he created the decimal system, Dewey founded the Library Bureau, a company that sells index cards and filing cabinets.
