Via lifehacker, I came across an interesting approach for reaching high shelves in a book case, or rather designing a bookcase whereby the bottom portion works as a step stool. Personally I’m a bit of a traditionalist and have a hankering for a proper library ladder on wheels…admittedly I’d also like my own private library that’s big enough for several levels (and ladders), not to mention a spiral staircase and a decent sized globe.
