subject classifications

Subject classifications are systems used to organize and categorize information, such as books, articles, or data, based on their topics or content. They help libraries, databases, and institutions efficiently locate and manage materials by assigning standardized codes or categories. For example, a book about physics might be classified under a specific science category. This system ensures that similar topics are grouped together, making searches faster and more accurate. Overall, subject classifications create an organized structure that helps users find relevant information quickly and understand the scope of collections or data sets.
