Subject headings are words and phrases which constitute a "controlled vocabulary" to categorize books by subject. Subject headings often indicate the contents of books in terms that their titles do not use, which often may be very general. Subject headings in online databases are often referred to as descriptors, but they serve the same purpose in locating valuable resources. Using a "keyword" search will identify catalog entries that contain those specific terms which can add value to a search; however, the terms can be found anywhere (author, publisher, title, etc.), so your search results will be less targeted if you use keywords than if you search for subject headings or descriptors.
Use general subject headings for searching a broad topic or more specific subject headings for a specific text, film, or play. You will find (more) headings specific to the subject category within the left-hand facets in our online catalog, BobCat.
