  1. Use the Library of Congress Subject Headings to do a subject search? Subject headings are words or phrases that are established to represent a subject covered in library resources and are referred to as a “controlled vocabulary.” The Library of Congress, our national library, has created a list of the subject terms that are used in most library catalog records in the United States. The Library of Congress Subject Headings (LCHS) is a set of 5 large red volumes that are located on the counter shelves in the Reference Area on the Main floor, next to the computer lab. The subject headings listed in LCHS are used in subject searching in the library catalog.

  2. Below is an explanation of an entry in the LCSH: Subject Heading Explanation

  5. This is a search using the subject heading, Drug abuse, and the subheading, Prevention:

  6. A helpful tip: General or Free-floating Subdivisions • In the LCSH there is a long list of general or free-floating subdivisions that can help in combining topics and in searching for a special focus of a topic. These subdivisions are added after a valid subject heading. • A list of these general subdivisions is in the front of the first volume of the LCSH • A few examples of these headings are: --Health aspects --Moral and ethical aspects --Psychological aspects --Physiological aspects --Social aspects --History --Statistics --Public opinion --Description and travel --Social life and customs • This is how they are used: Abortion – Political aspects

  8. Use the LCSH to help you: • Find the established subject term to do a subject search in the library catalog. • Brainstorm for other terms or concepts related to your topic so you can narrow your topic. • Develop a list of key terms and concepts for you to use in searching databases and the World Wide Web.
