DDC+Dewey+Decimal+Classification

= =  The Dewey Decimal Classification (DDC) was developed by Melvil Dewey in 1873 and first published in 1876. Dewey was only 21 years old when he came up with the idea. The DDC is an organization tool used by libraries to help people find books. It is continuously revised and updated to keep pace with the changes that take place in our world. = =  Libraries in more than 138 countries use the DDC to organize and provide access to their collections, and DDC numbers are featured in the national bibliographies of more than sixty countries. It is the most widely used classification system in the world. The parts of the DDC are arranged by discipline, not subject, so a subject may appear in more than one class.

For example, "clothing" has aspects that fall under several disciplines.
 * The psychological influence of clothing belongs in 155.95 as part of the discipline of psychology;
 * customs associated with clothing belong in 391 as part of the discipline of customs;
 * and clothing in the sense of fashion design belongs in 746.92 as part of the discipline of the arts.
