This is a great question. Shares and dividends are important to know about if you are doing to invest. If you are writing a report on them and want to use the newspaper for research, there are a few things that you can do.
First, you will need to choose the correct newspapers. I would go with the Wall Street Journal and the New York Time. They are the most reputable and the former is about the financial world.
Second, since we live in the digital age, most of these newspapers are online. This means that you can do research through key words. So, I would say that that the easiest thing to do is type in words like, "dividend". If you have more time, what you can do is look at headline. This should get you started.
