Library of Congress Classification is a system that uses what in its scheme?

• A. Letters and numbers
• B. Words only
• C. Dates only
• D. Colors

Answer: (A)

The system uses an alphanumeric approach: call numbers begin with letters to indicate broad subject areas, and those letters are followed by numbers to narrow the topic. This combination of letters and numbers lets the library group related works together while providing precise, scalable subdivisions for a wide range of subjects. It’s not based on words alone, dates, or colors. The letters give the big category, and the numbers (often with decimals) specify subtopics in a hierarchical way.
