DefinitionControlled vocabulary for indexing and cataloging biomedical literature

Medical Subject Headings is a comprehensive controlled vocabulary used for indexing and cataloging biomedical literature in PubMed, a database maintained by the United States National Library of Medicine (NLM) at the National Institutes of Health (NIH). MeSH is used by librarians, information specialists, and researchers to facilitate information retrieval and knowledge discovery in the fields of medicine, nursing, dentistry, veterinary medicine, and related health sciences. MeSH is also used by database providers such as Elsevier and Wiley-Blackwell to index and catalog their scientific journals and academic publications.

Introduction to Medical Subject Headings

Medical Subject Headings (MeSH) is a hierarchical controlled vocabulary that consists of a set of terms and phrases used to describe the content of biomedical articles and research papers. MeSH is used to index and catalog biomedical literature in PubMed, which is a database of over 29 million citations for biomedical literature from MEDLINE, life science journals, and online books. MeSH is also used by other database providers such as Scopus and Web of Science to index and catalog their scientific journals and academic publications. The use of MeSH enables researchers to search and retrieve relevant articles and research papers from PubMed and other databases using a standardized set of terms and phrases.

History and Development

The development of MeSH began in the 1950s at the National Library of Medicine (NLM) with the goal of creating a controlled vocabulary for indexing and cataloging biomedical literature. The first edition of MeSH was published in 1960 and consisted of a set of terms and phrases used to describe the content of biomedical articles and research papers. Over the years, MeSH has undergone several revisions and updates, with new terms and phrases being added to reflect changes in the field of medicine and the health sciences. MeSH has been used by researchers and librarians at institutions such as Harvard University, Stanford University, and the University of California, Los Angeles (UCLA) to index and catalog biomedical literature.

Structure and Organization

MeSH is a hierarchical controlled vocabulary that consists of a set of terms and phrases organized into a tree-like structure. The top level of the MeSH hierarchy consists of 16 broad categories, including Anatomy, Organisms, Diseases, and Chemicals and Drugs. Each category is further subdivided into more specific terms and phrases, with the most specific terms and phrases being used to describe the content of biomedical articles and research papers. MeSH is also used by organizations such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) to index and catalog biomedical literature.

Maintenance and Updates

MeSH is maintained and updated by the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The MeSH vocabulary is updated annually to reflect changes in the field of medicine and the health sciences. New terms and phrases are added to MeSH to describe emerging topics and concepts, such as genomics, proteomics, and personalized medicine. MeSH is also used by institutions such as the National Cancer Institute (NCI) and the National Institute of Mental Health (NIMH) to index and catalog biomedical literature.

Uses and Applications

MeSH is used by researchers, librarians, and information specialists to facilitate information retrieval and knowledge discovery in the fields of medicine, nursing, dentistry, veterinary medicine, and related health sciences. MeSH is also used by database providers such as Elsevier and Wiley-Blackwell to index and catalog their scientific journals and academic publications. MeSH is used by organizations such as the American Medical Association (AMA) and the American Heart Association (AHA) to index and catalog biomedical literature.

MeSH Classification System

The MeSH classification system is a hierarchical system used to classify biomedical articles and research papers into specific categories. The MeSH classification system consists of a set of terms and phrases organized into a tree-like structure, with the most specific terms and phrases being used to describe the content of biomedical articles and research papers. The MeSH classification system is used by researchers and librarians at institutions such as Johns Hopkins University, University of Pennsylvania, and the University of Michigan to index and catalog biomedical literature. MeSH is also used by institutions such as the National Institute of Environmental Health Sciences (NIEHS) and the National Institute of Neurological Disorders and Stroke (NINDS) to index and catalog biomedical literature.
