When first going to the Browse Newspapers command, you will see the list of countries in your collection as well as the related states, provinces, etc. Every time you select state (or equivalent), the screen will widen to the right as shown above. Each term in grey indicates another choice has been made to specify the paper and edition.
To change back to a different date or paper or state or country, simply click on that term (going from right to left).
The Papers by location in the upper right corner of the Browse screen will take you to a map showing papers based on location. Clicking on each of the red map dots will take you to that region. You can then search within that region. HINT: clicking on the search magnifying glass with no search terms will take you to a list of that region's papers.
NOTE: The browser's back button does not work effectively with this page, so to go back, it is easiest to click on Browse again then restart on the Papers by location link.
