subject indexing

Subject indexing is the process of organizing information based on specific topics or themes, making it easier to find and retrieve relevant knowledge. In practice, this involves assigning keywords, categories, or classifications to various pieces of information, such as articles or books. For example, a book about climate change might be indexed under "environment," "global warming," and "sustainability." This allows individuals to quickly locate related materials when researching a particular subject, enhancing their ability to access and understand various aspects of general knowledge efficiently.
