Are you running out of room for your books? Here's a house design by Kazuya Morita Architecture Studio that hopefully doesn't have that problem. Google Translate renders the Japanese text as follows:
Shelf-Pod is a private residence and study building, located in Osaka prefecture, Japan. The client owns an extensive collection of books on the subject of Islamic history, so he requested that we create this building with the maximum capacity for its storage and exhibition.[...]
The original image of this structure is derived from the Japanese woodcraft of Kumiko. The structural integrity against an earthquake is provided by a panel of plywood board nailed on the shelf. Initially, the horizontal resistant force guaranteed by the panels was examined in a real-scale model. Further to this, an analysis of the whole structure was performed in order to determine the placement of the windows and panels. The inter-locking laminated pine-board was manufactured precisely in advance and assembled on-site. Similarly, the pyramid-shaped roof was assembled on-site, from 12 pieces of prefabricated wooden roof panel. The completed roof has a thickness of only 230mm and sensitively covers the whole space like the dome of a Mosque.
