Internet sites

[Lookatmeknow!!]

I am looking for some good referenced sites for a paper for my class. I am looking for stuff about the principles of the Constitution, self government, seperation of powers, and checks and balances. I am also looking for stuff about the 3 federal branches. I know there are wiki sites and ask sites, but I can't use those. They are not viable sites. I could also use some journal articles. If anyone could help, I would really appreciate it! Thanks so much!!
