Introduction

Imagine a committee of booksellers meeting to decide where to open a centre to sell second-hand books. The idea is to bring together collections of books on such a scale that they serve the whole country and the centre acts as a point of reference for all book buyers. The committee would no doubt agree that such a centre should be located where it is easy to reach. It seems so obvious that it is likely that little time would be wasted on this point.
