Subject headings are words or short phrases that are added to the records of every item in the database. Subject headings use a ‘controlled language’, meaning there is only one word or phrase used to describe a specific concept. In theory, this means that every reference discussing rehabilitation, for example, will have a subject heading related to rehabilitation.
Using the Explode and/or Focus functions with your subject headings may give your search results more relevance.
If you can’t find a subject heading to match your search term(s) using the instructions below, try again using some synonyms.
If that does not work, search by keyword instead.
For your chosen heading(s), you have the option to Explode the heading(s), Focus the heading(s), or both.
Depending on your selections, you may be taken to a list of Subheadings.
Choosing any subheading rules out any references that have no subheadings at all, as well as potentially relevant references with different subheadings. For this reason, we generally advise not to use them.
