ABSTRACT
It is a difficult and even daunting task to summarize this book. In it are fifteen chapters — sixteen if you include the introduction — which cover a wide range of topics and viewpoints. Each chapter has presented a perspective on expertise and technology, and although many of the chapters support and complement each other, none of them are redundant. We have tried to put them together in three main groups, but the fact remains that the book in a sense presents fifteen dimensions of expertise and technology. As if this was not enough, there is no guarantee that there may not be additional ones. We are thus faced with a set of problems that is more complex than we really would like it to be. As the fifteen contributions have made clear, we are not near the stage where a unified view on expertise and technology can be proposed. This is perhaps characteristic of the field itself: Expertise is not a one-dimensional phenomenon and cannot be given a single — or simple — description.
