The Dewey Decimal Classification (DDC) system, commonly referred to as DDC Codes, plays a pivotal role in organizing library materials. Established by Melvil Dewey in 1876, this system categorizes books into ten main classes, making it easier for users to locate what they need.

Each DDC Code consists of three digits, which represent a specific subject area. For instance, the code '500' is designated for natural sciences and mathematics. Understanding these codes helps librarians, researchers, and library users navigate vast amounts of information effectively.

In today's digital age, while many resources are available online, DDC Codes remain a fundamental part of library science, ensuring that physical collections are easily accessible. Whether you’re a student, librarian, or just a curious reader, familiarizing yourself with DDC Codes can enhance your library experience.
