NLM Classification

NLM Classification is a systematic way the National Library of Medicine organizes its vast collection of medical and health-related materials. It assigns specific codes to topics, fields, or subjects, enabling easy categorization, retrieval, and management of resources. Much like labeling files in a well-organized filing cabinet, these codes help researchers, librarians, and healthcare professionals quickly find relevant information on topics such as diseases, treatments, or medical specialties. The system is structured hierarchically, allowing for detailed classification while maintaining an overall organization of medical literature.
