Company profiles
Look in the Business Demographics section for the Last Updated date.
If the title of the company profile is sufficiently unique to identify the company profile (i.e. there is only one of that company in that city & state), then the company name with city is the title:

If there are multiple locations of that business in that city/state, include the exact address in parentheses as a form of unique number identifier:

Company lists or directories
Since there is no official title, create a description in square brackets, non-italicized, to describe how you compiled this data. See section 9.22 in the Manual. The square brackets in this case indicate that somebody else searching the resource cannot use these exact words to search for it; but they could figure out what you did.
