A subject catalogue arranges library materials based on their subject content using a controlled vocabulary, such as Library of Congress Subject Headings, to consistently describe topics. This allows users to easily find materials on a specific subject regardless of title or author and through related subject cross-references. The main goal is to efficiently locate relevant materials through an effective subject search of the library collection.
