Find out if using the Google Reader API

I understand that when typing feed for an atom, you can specify the number of items to return, and the items will have a continuation field that you can use to trigger subsequent selections at a position after the items you've already selected. The question is, how do you know if there is anything else to extract without trying to get more?

Every feed you get from the Google Reader API will contain a continuation token if there is more on the server. If this token is not found in the stern of the atom, it is no longer there.
