Subject Headings
1. What are Subject Headings? Subject Headings are controlled vocabulary terms used to classify items.
2. What are Subject Headings? Catalogs (e.g. MNCAT) include Subject Headings in their records to describe the content of books, journals and other types of materials.
3. What are Subject Headings? Article databases (e.g. Academic Search Premier) use Subject Headings, or Descriptors, to describe the content of articles.
4. Why Use Subject Headings? A Subject Heading identifies a concept rather than a specific word. It allows you to search broadly. For example, in an ordinary keyword search, the term "teenager" will only return results with the word "teenager" included.
