The Dewey Decimal System is indeed employed for fiction books. It provides a structured way to categorize and locate them within library collections. However, its usage might vary depending on the specific library's organization and policies.
The Dewey Decimal System classifies fiction books generally under the 800s. For example, 813 is often for American fiction in English. Libraries use this system to organize their collections, making it easier for patrons to find different works of fiction.
The Dewey Decimal System is mainly designed for classifying non-fiction. Fiction is often organized differently. For example, it might be sorted by author or genre rather than using the Dewey Decimal System.
