What does the Dewey Decimal System of classification provide?

The Dewey Decimal System of classification is designed specifically to organize library collections by disciplines or subjects. This system categorizes books and materials into ten main classes that address a broad range of topics, each represented by a three-digit number applied to the works within that category. For instance, 000-099 covers general knowledge, while 900-999 pertains to history and geography. By using this method, libraries can facilitate users' access to materials that relate to specific subjects, making it easier for patrons to find resources connected to their interests or areas of study.

This structure contrasts with alternatives like arranging collections by author or publication date, which focus on different facets of a work rather than its content. Similarly, classifying materials based on popularity does not contribute to the systematic organization of scholarly resources. Therefore, the choice that highlights arrangement by discipline accurately reflects the fundamental purpose of the Dewey Decimal System.
