what were the long-term repercussions of the Potsdam Conference?
Since this is not my area of expertise, I searched Google under the key words "Potsdam Conference" to get these possible sources:
http://en.wikipedia.org/wiki/Potsdam_Conference
http://www.history.navy.mil/photos/events/wwii-dpl/hd-state/potsdam.htm
http://history.howstuffworks.com/world-war-ii/potsdam-conference.htm
http://www.spartacus.schoolnet.co.uk/2WWpotsdam.htm
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
