1. Harvesting peas in Peoria
(Note: Peoria is in the state of Illinois)
In LCSH:
Peas (May Subd Geog)
— Breeding (May Subd Geog)
— Diseases and pests (May Subd Geog)
— Genetics
— Harvesting (May Subd Geog)
This one is easy. The subject heading Peas already has a subdivision for Harvesting established.
Our task, then, is to determine if it can be subdivided geographically.
The Harvesting subdivision says (May Subd Geog) so we can geographically subdivide at that, our most specific, element.
Peoria is a city in Illinois. Can we subdivide Peoria directly?
No. We must go through the collecting level.
What is the collecting level for a city in the United States (other than New York)?
The state.
Thus we have:
Peas—Harvesting—Illinois—Peoria
— Illinois ― Peoria
Peas — Harvesting

2. The psychic aspects of celery in Salerno
(Note: Salerno is in Italy)
In LCSH:
Celery (May Subd Geog)
In LCSH our pattern heading for plants:
Corn (May Subd Geog) …
— Psychic aspects (May Subd Geog)
Our subject heading is Celery.
But there is no subdivision for psychic aspects?
What is our pattern heading for plants and crops?
Corn
Is there an appropriate subdivision under Corn?
Yes. Psychic aspects.
Can we subdivide psychic aspects? Yes.
Psychic aspects (May Subd Geog)
Salerno is a city in Italy.
Can we subdivide by Salerno directly? No.
What is the collecting level for a city in a country other than the U.S., England, or Canada?
The country.
So we end up with:
Celery—Psychic aspects—Italy—Salerno
—Italy ― Salerno
Celery — Psychic aspects
