indexing directory question
I am indexing a Canadian Business Directory. At the top of the page. the title is Province of Ontario-- Dominion of Canada, which I am assuming I enter as Ontario, Canada in the Directory Place box. But, the directory is divided into what looks like townships and counties. For example, before a group of names, is the title, "North Agusta' "(Greenville Co.)" and then some names, and then another subheading with a different town and county. Do I enter the town and county in the Directory Place box along with Ontario, Canada for each different group of names? Would the entry look like this, North Augusta, Greenville, Ontario, Canada? Or would I just enter the title of the directory Ontario, Canada for all groups? And do I uses a comma between each location?
