Most of us just start typing when we encounter a search box. However, understanding the differences between
keywords - words anywhere in a record or text and
subject headings or descriptors - phrases assigned to a catalog record by a human being who has assessed the content
can help you to focus or to expand your search. Using subject headings will pull together related records with terminology you may have not considered in your keyword search.
Below are some examples of keyword searches and related subject headings.
