Books, videos, and other materials in library catalogs are assigned
official subject headings by the Library of Congress. These subject
headings describe an item's content and what it is about, and are useful for focusing research on
broader, narrower, or related topics. Look for subject heading links in the library catalog to find more items on the same topic.
For example, the book Dance and the Hollywood Latina has the following LC Subject Headings to describe it:
Subdivisions, or subheadings, are words or phrases which may be added to a subject heading to create a more effective search. Some standard subheadings are:
| Abstracts | Encyclopedias | Research |
| Bibliography | Fiction | Sex differences |
| Biography | Handbooks, manuals, etc | Social aspects |
| Case studies | History | Social life and customs |
| Diaries | In literature | Study and teaching |
| Dictionaries | Law and legislation | Statistics |
| Directories | Pictorial works |
For assistance and other tips on how to construct more efficient searches, ask a reference librarian.
