I have so many books but I don't think I could ever part with them - (or at least the majority of them!) I have a Kindle but there's I still much prefer 'real books'. If e-books did take over - (which I don't think they will) - I'd really miss browsing bookshops. I can never pass a bookshop without going in.
Whenever I do settle down in my own house I will want a library of some sort. Either something like Neil Gaiman's which has a double layer of books -
Or something like these stairs-
Though most likely I will need both.
