I'd go for a double-helix staircase. Reference on one side, fiction on the other.
You could get pretty nuts with bookcase staircases. Alternating tread double-helical staircases with books on the inside and outside faces of the stairs, and shelves on the underside of the treads above as well? Probably not to code, but it's would be pretty cool.
