We have noticed that a lot of articles in home magazines are cropping up around how you should or could display the books on your shelves.  One popular idea seem to be to colour order the spines of your books to make a feature without any added cost. This could well be a good way to spend a rainy afternoon, and change the look of a room at the same time.  Colour co-ordinating generally can give a room a more spacious feel, as can keeping your colour palette to a few shades.
