The Subject search option is used to retrieve records using Library of Congress (LC) Subject Headings. The LC Subject Headings are terms or phrases that have been designated as the standard word or phrase for every subject.
For example, if you were doing research on doctrinal theology, you would not want to put doctrinal theology in as your subject, because the designated LC Subject Heading for this topic is actually theology, doctrinal.
Often, if you put in the wrong subject heading, Orbis will let you know what the correct subject heading is for your topic.
Orbis will also suggest alternative subject headings and will provide headings for more specific subdivisions of the subject.
