the february issue of world of interiors carries a nice little feature on library ladders. among my favorites shown (for those of us without a rail for a rolling ladder) are these three. the putnam no. 70 (top) folds ingeniously from side to side for easy storage in a corner. the folding stepstool (middle) from summerill & bishop is simplicity itself. for a light, modern and affordable ladder, ikea's inreda ladder is tough to beat.
