I now have several hundred books on my reader many of which I have read and may read again and a lot which I haven't read yet as I tend to stock up with books when I am back in the country. It seems to me that it is a really basic requirement to be able to identify easily those books which have not been read yet but I can't see any way to do it. It would also seem a no-brainer that such a filter should be available at a menu level but it isn't. Even without that it would be useful to have a quick check to see if a book is read or not. Can anyone help? Thanks...
