Walter Leimgruber's book on marginality has grown out of the work of the International Geographical Union's Commission on Evolving Issues in Geographical Marginality, as well as seminars at the Department of Geography at the University of Fribourg, Switzerland, where he has been working for many years. It is a bold and very personal attempt to grasp the nature of marginality at different scales and in various times and spaces, exploring how this ties in with the wider trends of globalisation and deregulation. It is a call for marginality to be taken seriously both as a notion and as a theme for research, bearing in mind that its multi-faceted nature precludes one simple definition.
