The Dewey decimal system of classification arranges collections by which criterion?

The Dewey Decimal Classification (DDC) system is a library classification system widely used to organize books and other materials based on subject matter. It categorizes items into ten main classes, each representing a specific discipline, such as philosophy, science, languages, arts, and literature, among others. By arranging materials according to the subject area, the DDC enables users and librarians to easily locate and access resources that pertain to a particular topic of interest. This systematic organization is particularly beneficial for scholarly research and general inquiry, as it provides a clear framework for navigating diverse fields of knowledge.

In this context, the other criteria listed, such as publication date, book size, and reading level, do not serve as the primary basis for classification within the Dewey system. While these factors may influence how materials are presented or shelved in a library, they are not foundational to the organizational structure set forth by Dewey. The primary intent of this classification is to facilitate access to information based on academic discipline, making it the correct criterion in this instance.
