I get asked this a lot, and I guess the easiest thing is to just show you.
This is the Expedit Book Case from Ikea, and I have it in my "flex area", which is a loft type of area in my home off of the bedrooms. What I love about this piece, is that it is more adjustable that you can imagine. It could work in many hallways, you wouldn't necessarily need a "flex area".
