I'm still very much a Kindle Newbie....but I'm really keen! My main source is Amazon - thousands of books for free! So far, the most I've paid is £4.10 for one book (and worth every penny - it's out of print, I can't even find a copy in 2nd hand book stores and e-bay sell 'real' copies for £100+!) Gutenberg is a terrific site - but the copyright issue is a bit tricky. I can't always tell if a book is copyright exmpt in the UK - and Gutenberg only tell you the books ar USA exempt. The German Gutenberg link is good too (thanks Theo!) Downloading Calibre is, I think, essential! Not only for the newspapers but I can now use calibre to access books from other sites too. The freebie thread on MoneySavingExpert often gives you sites for free e-books - usually time-limited, the books are only available free that day/week.
