What is a good way to find information on previous ban lists?
Is there a good website to look at that might have all this information in one place?


Seems that the good ol' Wiki has a complete  collection of Historical Banlists.

It seems very exhaustive and complete. 

I also found a Historic Limited/Forbidden Chart which displays the information regarding forbidden and limited cards in a graphical way (green, yellow, red color code). Perhaps that is a better way to see the evolution of bans of cards.
