Ladder bookcases are usually narrow and not very high, and for that reason they are a good choice if you don’t have a lot of stuff to place on them. In that sense they are more decorative than practical. They are ideal for displaying nick-knacks and other small decorative items. Their angles serve to break up the vertical and horizontal lines of your other furniture.
Here’s a couple of examples. I like the Benzara model on the right. It seems to disappear against the white wall, which makes it very subtle and unimposing:
