Australian editions

Warning, it seems that the article that was the most used as a source for Australian releases (including the Zappa Patio for instance) is not accurate => http://www.science.uva.nl/~robbert/zappa/interviews/australia.html

However it seems that a guy managed to sort out things => http://www.zappainaustralia.com/

Not a big deal yet in the wiki as I always try to find several evidences including visual.
This lead me to think that I need to find a way to cite sources in the versions tab.
This could be a bit hard as a most of the information I got so far (ean codes & release dates for instance) come either from commercial (jbook.com) and auctions sites (eBay) that do not necessarily last or records I do own (matrix numbers) or see in shops (I take pictures from time to time)...
So for each single line in the tab, I may have more than 5 different sources which is not so easy to manage.
