Which term refers to the broad divisions used within a standardized classification system?

• A. Main Classes of DDC
• B. Genre-Based Organization
• C. Dewey Decimal Classification (DDC)
• D. Visual Appeal

Answer: (A)

Broad divisions at the top level of a standardized classification system are called the Main Classes. In the Dewey Decimal Classification, these are the ten broad subject areas that organize all topics from 000 to 900, such as general works, philosophy and psychology, religion, social sciences, language, science, technology, arts and recreation, literature, and history and geography. This top-level structure helps librarians place materials into a consistent framework and makes it easy to find related topics across the collection. Genre-Based Organization groups items by form or genre rather than by broad subject areas used in the formal cataloging framework. The Dewey Decimal Classification refers to the entire system, not just its broad divisions, and Visual Appeal has no role in how items are classified.
