Found this website the other day, its a resource of a huge amount of eBooks being sold on ebay with re-sell rights being sold for effectively nothing, just browse them free!

Some interesting things and plenty of eBooks I wouldnt pay for having seen the content!

[edit] And the funny thing is now people are selling links to that website on eBay!
