Subject Headings are how librarians organize information in the catalog and in the stacks to make information easy to find. When you search by subject, you're linked to all the other books or articles that have been assigned the same subject.
Do a subject search for "Bible as literature" or Bible Criticism interpretation to see how many books have been "tagged" with these subject headings.
***During your class demonstration, the second suggestion did not work. This has been fixed. Search for Bible Criticism interpretation without quotes to get results.

Knowing the difference between search fields helps you dig deeper into a database to find relevant information.
Keyword: searches anywhere and everywhere for the search term. You get lots of results but fewer will be relevant to your research.
Subject: searches only in the subject headings for the term. You will get results where your search term has been described as one of the main subjects of an item, meaning fewer results but much more relevant sources of information.
