Subject Headings are controlled vocabulary that enable you to search by SUBJECT. Subject headings are assigned to books when they are cataloged and there is an attempt to use the same heading for all books on a particular subject. Some books may require more than one subject heading, so often there are several you can use to get to the items you want. When you are searching for Bibles or books about the Bible, subject headings are necessary. If you search for "Bible" as a keyword, you will get thousands of hits, most of which will not be relevant to your search. Here are some examples of subject headings that may be useful for your work. You do not need to use the punctuation when you search in ORBIS, but you do need to put spaces between the different elements.
There is a specific syntax (order) of elements for Bible headings: Bible. OT/NT. (book). (verses)--(sub-divisions)
Books about the Book of Genesis:
Bible. O.T. Genesis
If you want to narrow your search to Commentaries (usually verse by verse expositions of the text), you can type:
Bible. O. T. Genesis -- Commentaries
Books about the Gospel of Mark:
Bible. N.T. Mark
Books that contain a more sustained argument about a book or portion of a book of the Bible are usually included under the sub-division, interpretation and criticism. For example:
Bible. N.T. Mark--Interpretation and criticism
Subject heading are not always intuitive, so please ask a librarian if you have trouble finding the material you need in the online catalog.
