II - 7 Kings of Rome: Sources

this is fun: http://www.youtube.com/watch?v=FmlHu0blCyE

Here is one of the main sources I used for the packets about the kings:
http://dante.udallas.edu/hutchison/Seven_kings/seven_kings_index.htm

The other go-to site is this one:
http://ancienthistory.about.com/od/kingsofrome/tp/KingsofRome.htm

I also think wikipedia is a useful source for this subject.
