Quick Summary

The user's query asks for a summary of "divided catalog" in library science. The provided search results discuss cataloging systems, including the dictionary catalog, the divided catalog, and the classed catalog. The answer should focus on the divided catalog as requested.

A divided catalog is a library catalog system where entries are separated into distinct files, typically one for subjects and another for authors and titles. This approach, while still using alphabetical order within each file, offers a more focused subject search compared to a dictionary catalog where all entry types are interfiled. Many libraries have transitioned from dictionary catalogs to divided catalogs to better accommodate the growing importance of subject-based research. This system has increased in popularity as it recognizes the value of a dedicated subject approach for library users.1
