the simplest thing you can do is to see if someone has already done the work for you.
This is where I learned that a simple website like Wikipedia comes in handy. Even though you need to take everything with a grain of salt and look for supporting articles that show the same information, it lays a foundation. On websites such as these we are tought to read with skepticism when really everything needs to be read with skepticism. These websites are perfect examples of websites where the work has been done, and everything has to be checked anyway, so you may as well start small.
