Library of Congress Subject Headings

The Library of Congress Subject Headings (LCSH) is a system used by libraries to organize and categorize books and other materials. It assigns standardized keywords or phrases to describe the main topics of each item. This helps users find resources on specific subjects quickly and accurately. Think of it as a detailed, systematic way to label and classify information so that when you search for a topic, related items can be easily located across different collections. LCSH improves both the cataloging process and search efficiency in large libraries and information systems.
