Some of the newspapers I found on-line were:
Overall, I didn't find any that listed marriages, but then I didn't check them all out either. Most did list obituaries, but was not a complete section. I would assume only the smaller papers would list all obituaries. And some papers did have where you could search for things, but since the internet is so new, most papers only have the last several years available so not much help when doing older research! Overall, it was interesting knowing that you can access so many different newspapers from so many different countries. It was fascinating seeing the different languages available on-line. On the whole, however, don't think this would be very helpful if looking for older records. Would be helpful if you wanted to know what is happening in a region that your ancestors came from. Or to travel to that area, the papers did mostly have travel information available. That would be helpful if you are planning a trip there. Also most listed the weather information which might be helpful if planning a trip to an area!
