To me, college research is a very personalized thing. It really depends on what you are looking for. If you are already at a college or community college I would start there.
Most schools and their websites have a lot to offer current students, don't be afraid to ask questions. My favorite websites are the ones I listed at the bottom of my article in the links section. Those are the ones that helped me the most in my own search.
One thing I did not mention is that if you are still in high school a lot of high schools give you a set amount of college visit days that count as an excused absence so I would definitely take advantage of those if you have them.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
