Narrowing or broadening a topic
Narrowing or broadening your topic
If you're finding too much information on your subject, you may want to narrow it:
EXAMPLE: Your topic is advertising in the United States. You may want to narrow it to the history of advertising in the U.S., or to the psychological aspects of advertising. In Addison, your subject headings would then be either "Advertising -- United States - History" or "Advertising -- United States -- Psychological aspects."
If you're finding too little on your subject, you may want to broaden it, or talk to a reference librarian about subject headings you might use to describe your topic.
EXAMPLE: Your topic is snake handling as a religious practice. You may want to broaden it to church history in either Appalachia or the Southern states. In the online catalog, Addison, your subject headings would then be either "Appalachian Region -- church history" or "Southern States -- church history."
