Module 1: Foundations of MeSH in MEDLINE®

MeSH Vocabulary


Subheadings (also called “qualifiers”) are associated with main headings to describe a specific aspect of a concept. Subheadings are a way of grouping together those citations that are concerned with a particular characteristic of a subject. For example, "Liver/drug effects" indicates that the article or book is not about the liver in general, but about the effect of drugs on the liver.

The subheadings in our example citation ( ) are the lowercase terms to the right of the slash ( / ). These include terms such as administration & dosage, adverse effects, and drug effects.
