Understanding MeSH
Many libraries use the Library of Congress Classification System or Dewey to organize and find information, however, if the topic is of a medical nature, you will want to use MeSH headings and terminology. "MeSH is the National Library of Medicine's controlled vocabulary thesaurus" - U.S. National Library of Medicine. It is a vocabulary that gives "uniformity and consistency" and is updated annually.
Many databases use MeSH subject headings. Instead of using the term, "Senior Citizen," the proper MeSH term is: "Aged". The scope note can give you more details if you are unsure if you are using the term correctly. In this case, "Aged" is: "A person 65 through 79 years of age. For a person older than 79 years, AGED, 80 AND OVER is available."
Databases that use MeSH terms include (but are not limited to):
- PubMed
