About Subject Headings and Thesauri
Subject headings, descriptors and thesauri terms are examples of "controlled vocabularies." They are lists of pre-defined, carefully selected words and phrases used to classify and organize information. Subject headings and thesauri terms describe the general content of a book, an article, an essay, or other information unit.
The keyword search is based on an exact word match; a subject or thesaurus search locates records by assigned subject or descriptors. Searching with subject headings or thesauri terms allows you to more precisely retrieve relevant information on your topic. Use subject headings and the thesaurus to:
- get ideas
- browse synonyms, broader terms, and narrower topics of interest
- get specific, targeted results
- combine with keyword searching for more focused results
- identify relationship between related terms
Identify all the major concepts of your thesis or research topic. Then use the thesaurus or subject index to locate, explore and select subject terms for each concept of your topic.
