For writers , it is a tool like Roget's — one with words grouped and classified to help select the right word to convey a specific nuance of meaning. For indexers and searchers , it is an information storage and retrieval tool: a listing of words and phrases authorized for use in an indexing system, together with relationships, variants and synonyms, and aids to navigation through the thesaurus. For more information on what a thesaurus is and what it contains, see: National Information Standards Institute.

If you're thinking about using database software you already have, or even building a thesaurus using word processing software, DON'T. Even a small thesaurus will represent a very large investment of time and intellectual effort. Software which will automate the clerical and repetitive tasks is available for a cost that's very reasonable when you consider the true cost and value of the tool you will be producing.

Each place is represented in the results list by its preferred name (in Vernacular or English, depending upon how the language is set; see #4 above) and place type . The preferred name is highlighted (in blue ). On the line below the name is the parent string for the place, listing broader contexts in descending order. The number in square brackets is the unique numeric identifier (Subject ID) for the place in the TGN database. All names that matched the query are in the results list. If a name that matched the query is not the preferred name, it will be listed under the parent string, in black letters.
Search Tips For the Find Name field, you may use AND and OR [e.g., 1) san carlos, 2) carlos OR charles, 3) carl* OR charl*, 4) san AND carlos, 5) carlos AND (san OR saint), 6) (carlos OR charles) AND (san OR saint)] Boolean operators must be in all caps (AND and OR). Wildcard is the asterisk (*); right truncation only. To find an exact match rather than a key word, use quotes [e.g., "carlos"]. There is an implied AND between the Find Name, Place Type, and Nation fields. About the TGN Learn about the purpose, scope and structure of the TGN. The TGN is an evolving vocabulary, growing and changing thanks to contributions from Getty projects and other institutions.

Thesaurus for Graphic Materials I: Subject Terms (TGM I) INTRODUCTION (1995 printed edition) I.

A thesaurus provides a standard language or set of terms with which to describe a subject area. Applied to indexing of a database, it indicates to a searcher which terms to use to retrieve the maximum number of relevant documents. The thesaurus terms are used by indexers to describe the contents of publications in a consistent, comprehensive and concise manner. These terms are listed in the Descriptors field (DE=) of each record added to the database. When logged into CSA Illumina, you may browse for terms via a hierarchical, alphabetical, or rotated index display using our interactive Thesaurus Search. These display formats allow you to navigate the thesaurus alphabetically or through the hierarchical relationships between terms.
