PubMed via LHL: Using MeSH

Medical Subject Headings (MeSH)

PubMed indexes articles using a controlled vocabulary,  Medical Subject Headings (MeSH®).  A specific set of terms is assigned to describe each article. This provides consistency and uniformity so all articles about a certain subject will be retrieved, even if different terms for the concept are used in the article, like myocardial infarction and heart attack. 

MeSH terms are arranged in a hierarchical categorized manner called "MeSH Tree Structures" and are updated annually.

Familiarity with this vocabulary will make you a better PubMed searcher.

You can find MeSH terms and search PubMed with them using the MeSH Database. Learn how by viewing the video below or view this page.
