Oh Cicero, who said "a room without books is like a body without a soul".
Amongst my (reasonably few) obsessions is the one I have for books. I can't remember never having loved reading...up to the library each week with my dad when I was a kid, taking out six books at a time.
And now I add the new obsession of scouring web sites to find pictures of beautiful houses with beautiful bookshelves. I did start to colour code my own books until a mischievous friend (you know who you are Mr T!) started to come around and take a blue spined book and put it with the browns...or an orange in amongst the white. Now the organiser in me just categorises! But I still do long for something like this...
but would be thrilled with any of these...
