Also, Lucy, you can get a long, long way by using free Calibre library/conversion software (you can download it from MR). Just grab books and select ePub format for your Sony. Pop into my own wee house's store as well (
www.bewrite.net) and let me know of anything that catches your eye. It'll be a pleasure to send the ebook/s over free of charge. ntmarrAtbewrite.net (use the @ sign). Good to have your company. Cheers. Neil
