Dimensions of Library Design

We are in the long and complex process of building a new house. The house will have space for a library, a rare book room, and a studio for my book repair work. I've been dreaming about having enough room for my books since I was a little girls. When we started the planning process, I thought it would be easy to explain what I wanted to the architect and interior designer. The library was so clear in my head. Of course it wasn't that simple.
