I'm most interested in getting content from Australia & NZ. I know Angus & Robertson is one such (
http://www.angusrobertson.com.au), I see there is also an Australian Gutenberg site (see gutenberg.net.au/). I have no dealings with any of these so can't comment on if they are good to deal with.
I would also like to see links to Canadian Amazon (Amazon.ca) and the Sony reader for Canada.
I got very confused by the 'search' feature of 'Get books' - it took a long while to realise I was searching what was already listed instead of doing an online web search. I could not understand why no aparaent action was taking place and I was not getting any results!
