I need to write a 10 page term paper on this topic: Describe the relative weaknesses and strengths of the North and South at the beginning of the Civil war. How did these factors influence the outcome of the war?

The thing I need help the most on is resources. I need 2 online resources and 3 sources from books (must be from professional/academic sources). It would be a big help if I could get some suggestions on which books I could use to help me write it because I have to do footnotes/end notes for the paper.

Also, any additional help on how I could outline the paper would be great.
