Indexing
with MeSH Vocabulary
NLM indexers
examine articles and assign the most specific MeSH heading(s) that
appropriately describes the concept(s) discussed.
- As many as
15 headings may be assigned.
- When there
is no specific heading for a concept, the indexer will use the
closest, general heading available.
Indexers
can also assign Subheadings
to further describe a particular aspect
of a MeSH concept.
- Examples
of Subheadings are: diagnosis, surgery, metabolism, pathology.
In addition
to assigning MeSH terms that describe the topic of the article,
the indexer provides terms that reflect:
- the age group
of the population studied
- the nature
of the studies: e.g., human vs. animal, male vs. female
- the material
represented (Publication Types) e.g., Clinical Trials, Editorial,
Review
In a later
section of this tutorial, you will learn how to use PubMed's MeSH
Database to find MeSH terms for searching.
