It has always been my experience that, whatever groupings I choose for my books, the space in which I plan to lodge them necessarily reshapes my choice and, more important, in no time proves too small for them and forces me to change my arrangement. In a library, no empty shelf remains empty for long. Like Nature, libraries abhor a vacuum, and the problem of space is inherent in the very nature of any collection of books.
