Introduction

This alphabetical index provides a listing of all the descriptors (preferred terms) in the Thesaurus. Descriptors are "Official Terms" of the Thesaurus that have been selected by indexers to represent the subject matter of database records. Consequently, these terms are used to index the database and are recommended for use in search strategies to retrieve desired records.

Finding a Term in the Alphabetic Index (All Descriptors)

Use the Find Term feature located at the top and bottom of the screen to locate a term within the Alphabetic Index (All Descriptors). Just type the term you are looking for in the text box provided and click on the Find Term button findterm.gif (1141 bytes).
  • If the term entered is in the thesaurus, you will be taken to its Term Report.
  • If the term entered is not in the thesaurus, you will be taken to its closest alphabetical match in the Word Permutations Index.
  • If the term entered is a plural, singular or international spelling variant of a descriptor used in the Thesaurus, you will be taken to its exact/closest alphabetical match in the Word Permutations Index.
  • If a multi-word term is entered, the information displayed will be based on the first word.

A navigation bar containing alphabetical links is also provided at the top of the screen. Click on any of these alphabetic links to browse through the list of all the descriptors (preferred terms) beginning with that particular alphabet. Scroll through the list or use the Find Term button findterm.gif (1141 bytes) to go to the term you are looking up.
