Which statement best describes a difference between Library of Congress classification and Dewey Decimal Classification?

• A. The Library of Congress system was developed to meet the needs of a specific library's collection
• B. The Library of Congress system is used only in national libraries
• C. Dewey uses letters instead of digits
• D. Dewey was created for large research libraries

Answer: (A)

The main idea is why one system was built for a specific library’s needs while the other was designed for broad, universal use. The Library of Congress Classification grew out of organizing the Library of Congress’s own very large and diverse holdings, so it was tailored to meet the particular needs of that library’s collection and can handle highly specialized topics. Dewey Decimal Classification, on the other hand, was created to be a practical, general-purpose system usable by libraries of many sizes and types, with a decimal structure that makes it easy to expand and adapt. So the statement that best describes a difference is that the Library of Congress system was developed to meet the needs of a specific library’s collection. The other options don’t fit: it isn’t limited to national libraries, Dewey uses digits (not letters), and it wasn’t created specifically for large research libraries.
