I am in the process of building knee walls for my expandable. I would like to include some book shelfs, drawers inside the kneewalls. Anyone know of any good websites or books that will help me get started? Thanks, mt

In an attempt to better use space in a room with many book shelves, I'd like to build some rolling book shelves. One wall would have permanent book shelves attached to it, then directly in front of it (no walkway) I'd like to have some rolling book shelves that may be moved left or right to gain access to the shelves behind them. It might be like this: =============================== =====........=====........=====........===== Above, "====" is a rolling shelf that may move left or right only. Question: Have you seen anything like this before? Since each shelf is rather heavy, should I make them roll on wheels, maybe a track? Ideas? thanks,
