Good to have your company, Kiwi. Why not download the free Calibre libraey software (
http://www.calibre-ebook.com)? You can store, catalogue and convert formats with that instanly and simply. When you download a particullar title to your kobo (via USB cable), you can delete it from your Kobo, but it remains in your Calibre collection for download again. You can also, of course, store there books you've yet to read without needing to carry them in your device itself. Great stuff. Good luck and best wishes. Neil
