|The Thesaurus for Graphic Materials is a tool for indexing visual materials by subject and genre/format. The thesaurus includes more than 7,000 subject terms to index topic shown or reflected in pictures, and 650 genre/format terms to index types of photographs, prints, design drawings, ephemera and other categories. New terms are added regularly. TGM is searchable through the Prints and Photographs Online Catalog (PPOC). [Search TGM] [view PPOC introduction]|
Although the thesaurus content remains essentially the same, there are some minor changes in field structure and labeling. For example, Public Note is now called Scope Note. Additionally, new fields were added to clarify term usage. For further information on these changes see "Fields in Term Record Displays" (via PPOC - About the Thesaurus).
