Hanso Information?

Can someone point me in the right direction of where all the hanso information on Lostpedia came from? If it wasnt on lost then how is it here, like, when did this stuff happen and wheres the info coming from? Is it because i live in Australia and they only played this stuff in a special in the US or something? Just sucks i didnt see these episodes (if they were episodes or whatever they were) Someone help!
