The Getty Thesaurus of Geographic Names (TGN)

The Getty Thesaurus of Geographic Names (TGN) is an organized database that catalogs place names and locations worldwide. It provides standardized, detailed information about geographic places, including their names, boundaries, historical names, and relationships to other locations. Used mainly by museums, libraries, and cultural institutions, TGN helps ensure consistency and accuracy when referencing places across different collections, research, and digital projects. Its goal is to improve the clarity and discoverability of geographic information, supporting the documentation and study of cultural heritage and history.
