We’re a small shop so we want to create a world that is as wide as possible with the books on one shelf. We are conscious of the distance between the books next to each other, the context that comes out of a few books clumped together, and we try to make the bookshelf interesting. We have also done our utmost to eliminate common genre divisions.
