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.
Examples:
Springfield (Bradford county, Pennsylvania, United States, North and Central America) inhabited place
Springfield (Delaware county, Pennsylvania, United States, North and Central America) inhabited place
Athens (Clarke county, Georgia, United States, North and Central America) inhabited place
