What are subject headings?
When you use Google or Google Scholar or databases such as Scopus or PubMed, you usually type in the obvious-to-you words to get some results. But does everyone else writing on or researching the same topic use the same words that you do?
For example, you might use teens but someone else might use adolescents.
Subject headings can help.
Subject headings are standard terms for particular themes/topics.
When the details of an article (or book) are entered into a database, it is tagged with subject headings for the main topics that it covers, no matter how the author refers to the topic.
Different databases use different subject headings. So in another database, the Subject Heading may be Teenagers.

Not all databases use subject heading searching, eg Google Scholar and Scopus. Recent articles in some databases eg Medline (Ovid) have not yet been through the full indexing process and have no subject headings. Best research practice
Subject headings in Medline and PubMed are called MeSH. |
