Geographic Reference

Choose the appropriate geographic area from the Geographic Authority File. The Geographic Authority File is based on the Getty Thesaurus of Geographic Names® (TGN).

Use a geographic access point when materials have a geographic focus or a considerable body of information about a geographic location is contained in the microform product.

This data is called an "access point." Best practice is to "anchor," or explain, all access points narratively in the descriptive record in which the access point appears. You should anchor this access point in the Microform Product Title or Abstract field.
