I am looking for a couple of website that have to to with these three questions on JP Morgan and company

1) What were the positive and negative effects of the business in the late 19th century

2) How has the individual you selected and his particular big business positively or negatively affect society today.

3) What were the pros and cons of big business in the 19th century and do they still exist.

I have the majority of my essay done, but can't find websites to back up these questions.
