Subject headings to refine searches

Records in Summon, Addison, WorldCat, and other databases like EBSCOhost use Library of Congress Subject Headings to describe and categorize their contents. You can take advantage of these subject headings and their subdivisions to refine your searches in these tools. Add these subdivisions to your searches (put the phrases in quotes) to limit to records with these formats or topics.
